Description

We have been intermittently getting a NPE in ScanThread.setUpFrame:360. This seems to be independent of compiler, operating system and instruction architecture. [1] demonstrates the bug in AIX in the SPECjvm98 tests. It is reproduced with a higher frequency in dacapo tests in the stress test-run (i.e. see [2]).

Several fixes in this area have occurred, and I havent seen a similar failure for a while.

It is quite likely that if there is an underlying bug it will be exposed differently so I am closing this issue.
