Rick Curtis closed OPENJPA-888.
-------------------------------
Resolution: Won't Fix
I'm closing this issue for a number of reasons...
1.] This is a serp bug, not an OpenJPA bug.
2.] Serp is pretty much dead and no one is going to cut a new serp release for
this one problem.
3.] There is a valid workaround.
Thanks,
Rick
> Empty method in an entity causes errors while enhancing
> -------------------------------------------------------
>
> Key: OPENJPA-888
> URL: https://issues.apache.org/jira/browse/OPENJPA-888
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 1.2.0
> Reporter: Simone Gianni
>
> I have a class subclassing another class. Both are entities. They have a
> method, which has nothing to do with JPA cause it's not a getter o a setter.
> The subclass overrides this method with an empty implementation, that is
> @Override public void theMethod() {} .
> As a result, OpenJPA throws an error while enhancing the subclass, more
> specifically the stacktrace is relative at SERP internals :
> java.lang.ClassCastException: serp.bytecode.CodeEntry cannot be cast to
> serp.bytecode.Instruction
> at serp.bytecode.Local.getEnd(Local.java:114)
> at serp.bytecode.Local.updateTargets(Local.java:155)
> at serp.bytecode.LocalTable.updateTargets(LocalTable.java:163)
> at serp.bytecode.Code.read(Code.java:2031)
> at serp.bytecode.Attributes.readAttributes(Attributes.java:152)
> at serp.bytecode.BCMember.read(BCMember.java:365)
> at serp.bytecode.BCClass.read(BCClass.java:123)
> at serp.bytecode.Project.loadClass(Project.java:211)
> Looking the Serp code and debugging it, I can confirm it is a SERP error, and
> opened a bug on its tracker
> (https://sourceforge.net/tracker2/?func=detail&aid=2556092&group_id=31479&atid=402282
> ).
> I'm opening this bug here to track the problem, and eventually use an updated
> version of SERP if/when they solve the problem.
> The most obvious workaround (which works) is to write something inside an
> empty method, a plain "int i = 0" will do the job.
