It seems that when using collect2 the global constructor for libgcj
calls _Jv_RegisterClass more than once for the same class.  The default
class hook, _Jv_RegisterClassHookDefault, messes with klass->next_or_version.
The attempt at reregistration is not detected before _Jv_CheckABIVersion
is called causing the abort.
