Java crashing after 6.0 upgrade

[epitaxial]

I just upgraded my 5.9 amd64 box to 6.0 and updated all the packages. However now java crashes with "Abort trap"

/usr/local/jdk-1.8.0/bin/java
Abort trap

Running "java" from jdk-1.7.0 does the same thing.

Ok apparently the fix requires a change to the fstab entry.

Correct. /usr/local needs to mounted with the wxallowed option given that Java violated W^X. This is caught by pledge(2) which aborts execution.

To my understanding this is caught by the kernel's virtual memory management subsystem, rather than by any pledge(2) syscall, but the end result of a policy violation is the same - the application is aborted.

The 6.0 Upgrade Guide describes the required configuration change to provision the wxallowed mount flag. Admins should always review the applicable Upgrade Guide before upgrading.

For 6.1, individual application binaries that require this type of WX memory access will each require the wxneeded link edit flag, for finer control of memory management. The -current Ports tree has recently completed this wxneeded transition.
