Bad Message 414 : reason URI Too Long (Large files)

[SJrX]

Describe the bug
This is a duplicate bug, but for some reason none of the existing bugs show up with this error so I wanted to make it searchable, with the solution.

To Reproduce
Create a large plantuml diagram with a URL longer than 8 KB.

Expected behavior
It should render.

Actual Behaviour
Bad Message 414
reason: URI Too Long

Workaround
At least for the Jetty version, you can supply the following environment variable to the container.

• _JAVA_OPTIONS=-Djetty.httpConfig.requestHeaderSize=65536

Additional context
Add any other context about the problem here.

Workaround for #87 #25 plantuml/plantuml-stdlib#79

@SJrX - couldn't you provide an example of docker start shell command, i still can not pass this options to dockerized server

thanks!

[grivo]

just an update for workaround from above

it's much better to use JAVA_TOOL_OPTIONS in case of docker's jetty read only version since nor JAVA_OPTIONS neither
_JAVA_OPTIONS works, yet JAVA_TOOL_OPTIONS works fine

so i have ended up with sort of requestHeaderSize set to 64k

docker run -d -p 127.0.0.1:8090:8080 -e JAVA_TOOL_OPTIONS=-Djetty.httpConfig.requestHeaderSize=65536 plantuml/plantuml-server:jetty

@SJrX please Close this

[SJrX]

@VladimirAlexiev can you explain why you want this closed. If you are a maintainer can you close it with a rationale. It seemed to have helped at least two people.

@SJrX Sorry, I don't remember why I said "Close".
@arnaudroques can you increase requestHeaderSize set to 64k on the deployed Plantuml server? Does it use Jetty? It won't cause any memory problem, right?
