Please review the following fix for 8087153:
http://spiro.us.oracle.com/~cplummer/webrevs/8087153/webrev.00/webrev.hotspot/
https://bugs.openjdk.java.net/browse/JDK-8087153
This bug was introduced by the changes for 8054386, which mapped the
archive RW even if RO was requested. The state of the
space_info->read_only was not reflecting this, causing an unnecessary
attempt to remap to RW later on when a method's bytecodes were
rewritten. This remap exposed a race condition on win32.
Since the changes are small, they will be committed once they are approved.
thanks,
Chris
