Subject [jira] Created: (OPENJPA-888) Empty method in an entity causes errors while enhancing
Date Mon, 02 Feb 2009 00:01:59 GMT
Empty method in an entity causes errors while enhancing

                 Key: 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(
        at serp.bytecode.Local.updateTargets(
        at serp.bytecode.LocalTable.updateTargets(
        at serp.bytecode.Attributes.readAttributes(
        at serp.bytecode.Project.loadClass(

Looking the Serp code and debugging it, I can confirm it is a SERP error, and opened a bug
on its tracker (

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.
