StackOverflowError in a Mock call

[mfriedenhagen]

Describe the bug

• We have a test where the single method mocked collaborator is called three times in a row with slightly different parameters.
• This changed behavior was introduced while updating from 2.4-M1-groovy-4.0 to v2.4-m2-groovy-4.0
• We use Maven 3.9.6, Java release is Temurin-17.0.10+7, test fails on both Linux Debian 12 as well as on macOS 14.3.1 (23D60).
• The first method call does succeed but the second leads to a StackOverflowError:

[ERROR] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.034 s <<< FAILURE! -- in org.example.ValidatorTest
5605 [ERROR] org.example.ValidatorTest.Overflow? -- Time elapsed: 1.017 s <<< ERROR!

I will have a look at that next week. It has probably something to do with the dependency change from gentyref to geantyref in 2.4-M2.

[AndreasTu]

This is an issue in the geantyref library. I have opened an issue there: leangen/geantyref#27
