Crash when zip file is modified while being used
Last modified: 2016-05-10 16:30:24 EDT
The JDK memory maps zip files (including jars) into memory, which can cause a crash if they are modified.
OpenJDK 7 and Oracle JDK 6 support a sun.zip.disableMemoryMapping system property which disabled the memory mapping, working around the problem. It would be good to backport support for that to OpenJDK 6, to allow customers to work around the issue.
Re-assigning to Andrew Hughes for backport once aph has ackd.
Andrew (Haley), any objections to having this backported?
