RFR(XXS): 8032518: fatal error has been detected by the Java Runtime Environment (access violation)

[Markus Gronlund]

Greetings,

 

Kindly asking for reviews for this very small fix:

 

Bug: https://bugs.openjdk.java.net/browse/JDK-8032518 

Webrev: http://cr.openjdk.java.net/~mgronlun/8032518/webrev01/

 

Background:

 

Still a bit puzzled about the manifestations of the crashes when inspecting the .mdmp files, which seems to be dereferencing a (debug) ResourceObj allocation[0] cookie address (~allocation address) at point of crashing. In addition, if the issue is an effect of not handling OOM correctly, I would expect to see a _pending_exception off the problematic thread, but there seems to be none. Also unknown why this seems to occur more on Windows x64 than any other platform.

 

Testing:

I have iterated the testcase nsk/stress/jck60/jck60014 locally - without suggested fixes I get about 10 crashes in about 300 runs. With fixes I am yet to see any crashes, currently ~600 iterations.

 

I suggest to putback this first (since it should be fixed anyhow), to see the effect, before any more time is spent on tracing this down.

 

Thanks

Markus
