PING: RFD: C2 bug: 8157306 random infrequent null pointer exceptions in javac

[Andrew Haley]

Hi Vladimir,

The current status:

This patch fixes a serious bug in AArch64 and perhaps other
targets.  It's blocked because you discovered that an assertion
(added by this patch) was triggered by some tests.  I do not believe
that anything this patch does could cause whatever problem the
assertion reveals.

I have not been able to reproduce the problem that you saw.  Therefore
there is nothing that I can do to fix it.  May I simply take the
assertion out and resubmit the patch?

This bug in C2 is real, and serious.  This patch is a blocker for
AArch64.

Thanks,

Andrew.
