.
Stack Trace: N/A
.

Local fix

  • This issue can be worked around with transactional lock elision
(TLE) disabled.

Problem summary

  • This problem is caused by the system call while in kernel code
going to put TM suspend mode, hence any change resulted will not
be rolled back when we exit kernel code and back into
transaction and the transaction is aborted, causing inconsistent
state.

The problem exists on ALL Java 7.1 Power Linux Java builds.
The problem does not apply to any other architecure or other
Java releases.

Problem conclusion

  • This APAR will be fixed in the following Java Releases:
   7 R1 SR1 FP1   (7.1.1.1)

The JVM has been updated to disable TLE for Linux on Power8.
