>                 URL: https://issues.apache.org/jira/browse/HARMONY-3747
>             Project: Harmony
>          Issue Type: Bug
>          Components: DRLVM
>         Environment: windows/ia32, linux/ia32
>            Reporter: Ivan Zvolsky
>         Attachments: Stub.class, Stub.java, Test.java

> The attached test (Test.java) attempts to load a class Stub (attached also). If the Stub.java
was compiled using some particular compiler (I used one from JRockit 1.4.2_04), the verifier
fails with:
> java.lang.VerifyError: (class: Stub, method: foo()V) Data flow analysis error
>         at java.lang.ClassLoader.defineClass0(ClassLoader.java)
> I attached also binary version of Stub class compiled by javac from JRockit 1.4.2_04
> I've checked that this is reproduceable at least on the following builds:
> svn = r531681, (Apr 24 2007), Windows/ia32/msvc 1310, debug build
> svn = r531681, (Apr 24 2007), Windows/ia32/msvc 1310, release build
> svn = r531681, (Apr 24 2007), Linux/ia32/gcc 3.3.3, debug build
> svn = r531681, (Apr 24 2007), Linux/ia32/gcc 3.3.3, release build
