Subject [jira] Updated: (DERBY-3081) cannot create instance of generated class because of java.lang.VerifyError in 4 tests on IBM iseries
Date Mon, 24 Sep 2007 18:49:50 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3081?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden updated DERBY-3081:
----------------------------------

    Attachment: javap.out
                ac601a400fx0115x38bex8045x0000004554b80.class

I was able to generate the class on Windows   I am attaching that class and the decompiled
with javap -private.

If I  ftp over to iseries,  java -verify yields:
> java  -verify org.apache.derby.exe.ac601a400fx0115x38bex8045x0000004554b80
  java.lang.VerifyError: org/apache/derby/exe/ac601a400fx0115x38bex8045x0000004
  554b80 0000 0000
          at java.lang.Throwable.<init>(Throwable.java:195)
          at java.lang.Error.<init>(Error.java:49)
          at java.lang.VerifyError.<init>(VerifyError.java:34)


I am guessing we are hitting something similar to DERBY-488 where the iseries JVM is more
strict than the other jvms.

Exactly how to determine the offensive code from this point is pretty fuzzy to me.  Any thoughts
are greatly appreciated.
