Rick Curtis commented on OPENJPA-2339:
--------------------------------------
Have you tried running on Java7?
> OpenJPA Ant enhancer task generates .class files with missing stackmap frame
> ----------------------------------------------------------------------------
>
> Key: OPENJPA-2339
> URL: https://issues.apache.org/jira/browse/OPENJPA-2339
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 2.2.0, 2.2.1
> Environment: OpenJPA 2.2.0 & 2.2.1, JaCoCo latest from git, Java 6
> Reporter: Dominik Stadler
> Assignee: Kevin Sutter
> Priority: Critical
> Attachments: TestJaCoCoProblem.zip
>
>
> I have a project which uses JaCoCo for code-coverage testing. Some of the
> tests load JPA Entities.
> Any JPA entities cause error messages "Missing or invalid stackmap frames."
> in JaCoCo code, which the developers of JaCoco indicate is a problem in the
> code enhancing the .class file before, i.e. here Open JPA Enhancer.
> OPENJPA-2085 seems related, but it is fixed in 2.2.0, which I am using. Was
> this only fixed for Java 7?
> I also upgraded to serp-1.14.1, which seems to have some related fixes, but
> the problem persists.
> See https://github.com/jacoco/eclemma/issues/35 for a related discussion.
> See the attached sample project/ant-file which reproduces the problem. Simply
> run "ant test" to trigger the error.
> A full stacktrace is
> [junit] Running MandantTest
> [junit] java.lang.instrument.IllegalClassFormatException: Error while
> instrumenting class Mandant.
