[JENKINS-75875] Declarative pipeline "Method too large" after removing stage #1487
Description
Note: this is not "Method code too large" but "Method too large".
We've had this "big" declarative pipeline (~1800 LoC).
We've added stages, removed stages, added functions, etc...
We do not use shared libraries.
We also have the `SCRIPT_SPLITTING_TRANSFORMATION` enabled (true) and the `...LOCAL_VARIABLES` disabled (false by default), although we don't have variables declared outside (or inside) the pipeline.
Most of the stages are in the form of
stage("Name") { agent { stuff } steps { sh "stuff" } when { stuff } }
And most of them are grouped inside parallel stages.
For professional reasons, I can't disclose the full pipeline.
Now, we removed a stage from the Jenkinsfile (as it was not needed/wanted anymore) and we started hitting this exception
General error during class generation: Method too large: WorkflowScript.___cps___146115 ()Lcom/cloudbees/groovy/cps/impl/CpsFunction;
groovyjarjarasm.asm.MethodTooLargeException: Method too large: WorkflowScript.___cps___146115 ()Lcom/cloudbees/groovy/cps/impl/CpsFunction;
at groovyjarjarasm.asm.MethodWriter.computeMethodInfoSize(MethodWriter.java:2087)
at groovyjarjarasm.asm.ClassWriter.toByteArray(ClassWriter.java:447)
(...)
I did some tests and the error appears after, at least, removing the `when` clause in the stage.
(Removing the whole stage also causes the problem).
I'm guessing this is a gray area between the `groupSize`/`declarationGroupSize` and the actual method sizes.
Given the different error message and slightly different stack trace, I couldn't tell if it was the same problem as JENKINS-37984 or JENKINS-56500.
