s390x openjdk8 system tests failing with java.lang.NoSuchMethodError: java/nio/ByteBuffer.position(I)Ljava/nio/ByteBuffer; and java/nio/FloatBuffer.position(I)Ljava/nio/FloatBuffer; #19888

cjjdespres · 2024-07-19T21:41:03Z

The failing tests:

MiniMix_5m_0 and MiniMix_10m_1 in openjdk8_j9_extended.system_s390x_linux_jit
MauveSingleThrdLoad_J9_5m_0, MauveSingleInvocLoad_J9_5m_1, and MauveMultiThrdLoad_5m_0, in openjdk8_j9_sanity.system_s390x_linux_jit

These are in the JITServer nightly tests, but a 100x grinder of MiniMix_5m_0,MiniMix_5m_1 without JITServer still produced failures (20/200).

The earliest failures I can find in the JITServer nightly tests in the two suites are:

https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk8_j9_extended.system_s390x_linux_jit_Personal/1062/
https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk8_j9_sanity.system_s390x_linux_jit_Personal/1065/

The commit ranges between the earliest failures and the previous successes are 69cba86...d946965 and eclipse/omr@7709363...38148ea.

Given the intermittent nature, I suspect JIT but not sure. Or maybe a machine/file system/network problem.
@hzongaro fyi, the failure rate is high, could this be JIT?

pshipton · 2024-07-23T15:28:44Z

The methods are inherited from java.nio.Buffer

hzongaro · 2024-07-23T23:15:49Z

I think the rewind and position methods inherited from java.nio.Buffer would have Ljava/nio/Buffer; as their return types. I'm not sure where those signatures might have come from. . . . Taking a look.

hzongaro · 2024-07-25T20:43:03Z

There's something fishy here. I was able to produce a core file with a grinder run specifying

-Xdump:jit+java+system:events=throw+systhrow,filter=java/lang/NoSuchMethodError#gnu/testlet/java/nio/ByteBuffer*

in EXTRA_OPTIONS.

Using jdmpview to look at a core file that was produced by that grinder run, I saw the following call stack on one of the threads:

Looking at the j9method and bytecodes for ByteBuffer/compact.test:

   ...

Note the signature of the call to ByteBuffer.position(I) is java/nio/ByteBuffer.position(I)Ljava/nio/ByteBuffer;. But that method is inherited from java/nio/Buffer in JDK 8 and 11, where it has a return type of java/nio/Buffer.

I tried building and running the test locally, I examined the class file for gnu/testlet/java/nio/ByteBuffer/compact.test in mauve.jar with javap, and saw the expected signature on the call to position(I):

  public void test(gnu.testlet.TestHarness);
    Code:
       0: bipush        10
       2: invokestatic  #2                  // Method java/nio/ByteBuffer.allocate:(I)Ljava/nio/ByteBuffer;
       5: astore_2

      11: pop
      12: aload_2
      13: iconst_3

I tried another internal grinder run, requesting that the workspace be preserved. I signed into the machine, and examined the class file for gnu/testlet/java/nio/ByteBuffer/compact.test in mauve.jar with javap, and saw the wrong signature for ByteBuffer.position(I):

  public void test(gnu.testlet.TestHarness);
    descriptor: (Lgnu/testlet/TestHarness;)V
    flags: ACC_PUBLIC
    Code:
      stack=4, locals=3, args_size=2
         0: bipush        10
         2: invokestatic  #7                  // Method java/nio/ByteBuffer.allocate:(I)Ljava/nio/ByteBuffer;
         5: astore_2
         6: aload_2
         7: iconst_0
         8: invokevirtual #13                 // Method java/nio/ByteBuffer.position:(I)Ljava/nio/ByteBuffer;
        11: pop
        12: aload_2
        13: iconst_3

Looking at the console log to understand where mauve.jar came from, I see this:

I'm wondering where the mauve.jar came from. Is it possible it was built with javac from JDK 17 or later, with the --release 8 option to allow it to be used with older versions?

For now, I don't think this is a JIT problem.

This kind of errors out there are normally when a code is compiled with higher version then 8 with -source 8 and -target 8. Once one compiles it with --release 8, the signatures should be correct. Since Java 9, the position(integer), flip, rewind, ... methods have overrides returning ByteBuffer in the ByteBuffer class. Until 8, they are inherited from Buffer and thus are returning Buffer. It means that SOMETHING in the chain is built with java >= 9 and not using --release 8. If the --release 8 is not possible, the code itself can cast the ByteBuffer to Buffer in the places those methods are called and it will work with java 8 after.

mauve.jar got built in https://openj9-jenkins.osuosl.org/job/systemtest.getDependency/45/

It looks like Temurin JDK8 is used.

+ /home/jenkins/workspace/systemtest.getDependency/j2sdk-image/jre/bin/java -version
openjdk version "1.8.0_422"
OpenJDK Runtime Environment (Temurin)(build 1.8.0_422-b05)
OpenJDK 64-Bit Server VM (Temurin)(build 25.422-b05, mixed mode)

@annaibm could you confirm JDK8 was used for building mauve.jar? https://github.com/adoptium/aqa-tests/blob/master/buildenv/jenkins/getDependency#L20.

@annaibm confirmed that JDK8 is used to compile mauve (we did not use a higher version of Java to compile)

build-tests:
     [exec] openjdk version "1.8.0_422"
     [exec] OpenJDK Runtime Environment (Temurin)(build 1.8.0_422-b05)
     [exec] OpenJDK 64-Bit Server VM (Temurin)(build 25.422-b05, mixed mode)
    [javac] Compiling 6694 source files to /tmp/mauve/mauve

Currently, we are trying to use JDK17 with --release 8 option to see if it works. If you have a better suggestion, please let us know.

Ok, so the analysis of this problem is following:
It is the class containing gnu.testlet.java.nio.LongBuffer.compact.test(compact.java:35)
that was built with java > 1.8 and maybe with source 8/target 8. In Java 8, the java.nio.LongBuffer.position(int) was inherited from java.nio.Buffer. So the return type was java.nio.Buffer. Jdk 9 introduced overridden methods with covariant return types for some of the functions that include the position(int). If you compile with source/target 8, you will get the right bytecode version, right language features, but you might get the APIs wrong. That is why --release was introduced.
The error message says that the code that calls that position(int) expects the function to return java.nio.LongBuffer, which will not happen if it is run with Java 8.
So, the fix is to compile the code that calls that function either with JDK8, or with JDK9+ with --release 8. Like that the compiler will resolve the call to that function as being inherited from java.nio.Buffer (and having the java.nio.Buffer return type)
The classes that got in JDK9 the overriden methods are java.nio.ByteBuffer, java.nio.CharBuffer and java.nio.LongBuffer. Possible others, but I did not hit the problem on them for the while.
I hope this explanation helps with understanding where the actual problem lies. It is not the bytecode version, it is the APIs that are not compatible with JDK8

So, that pull request basically fixes the build of the mauve.jar, so that it works with the java 8. It is hanging in eclipsefdn/eca. I am not sure whether we (SUSE) have ever signed something like this. I also don't care to be credited, so anybody who has the right paperwork on file can submit that patch. I transfer automatically the copyright to anybody brave enough to get it integrated.

Now for the record: this is one of the most annoying improvements of Java 9. The release=8 should solve it, but it hides from the user many of apis that were considered internal or deprecated, so it is not always possible to use it. When it is only one file that is problematic and one is lucky not to have any cross-dependencies between this file and the rest, one can do what I did. But this is not always the case. In that situation, there is still a fix that works with Java 8 and Java 9+, but it requires source changes. At any invocation of one of the following methods:
position(int newPosition)
limit(int newLimit)
flip()
clear()
mark()
reset()
rewind(),
the object must be cast to Buffer and thus the right method will be called. It is cumbersome but in some situations, the only solution.
