hs_err log from the crash
Description of problem:
I was compiling java package (tycho) with maven and java received SIGSEGV.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. this might be more tricky since it's entirely possible some of my changes are triggering this. If needed I can retry with default versions.
From the looks of it, one or more jar/zip files are being opened by the VM, changed on disk, and being accessed again from the VM object. Because the VM uses mmap to open zip files, once the file contents change, there are memory errors.
This is a known issue (in OpenJDK and Oracle JDK). It is hard to fix in a correct manner without trading significant performance.
Marking dupe of original.

I thought someone had backported this to 6 but I don't see it.
