Fails when loading a class from the shared class cache.

Local fix

  • Disable share classes (-Xshareclasses:none), or remove option
-Xcheck:vm:debuginfo.

Problem summary

  • The VM was missing one action when loading classes from the
shared class cache. The missing action causes a problem only
when option Xcheck:vm:debuginfo has been specified.

Problem conclusion

  • The VM has been corrected to add the missing step and prevent
the assertion.
.
This APAR will be fixed in the following Java Releases:
   7 R1 SR3 FP60  (7.1.3.60)
   8    SR3 FP12  (8.0.3.12)
