APAR status

  • Closed as program error.

Error description

  • Error Message: UnsatisfiedLinkError is thrown when attempting to
call a native which was bound via the JNI function
RegisterNatives and the declaring class has been redefined.
.
Stack Trace: N/A
.

Local fix

  • 



Problem summary


    

  • Classes which are recreated as a side-effect of recreating other
classes were not retaining their bound native implementations.
This is only visible if the native method was bound using
RegisterNatives as the VM would simply re-bind natives that were
found in loaded JNI libraries.

    



Problem conclusion


    

  • This defect will be fixed in:
7.0.0 SR1
6.0.1 SR2
6.0.0 SR11
.
JVM has been updated to retain the bound native information in
all cases.

    



Temporary fix
