Threads on xalan on BaseBaseGenRC x64 sometimes terminate with a lock still held

Description

Regression tests for x64 show some failures on x64 BaseBaseGenRC. Most of those seem to be GC-related.

However, there's also a failure on xalan that might indicate a threading problem. See
https://jikesrvm.anu.edu.au/job/x64-porting-main-repo/883/testReport/junit/(root)/xalan/xalan__BaseBaseGenRC___default____Tests__dacapo_/ for the original report.

I've attached the output.
