Charles Duffy updated IVY-1454:
-------------------------------
Attachment: IVY-1454-r3.patch
Somehow, despite still adding a "X must be static" comment, the static keyword
got lost between r2 of the patch being tested and posted.
r3 puts it back.
Thank you again for the very helpful test case, and please accept my apologies
for the churn.

> When trying to use {{artifact-lock-nio}} as the lock strategy, I get resolve
> errors due to {{OverlappingFileLockException}} being thrown:
> {code}
> [ivy:resolve] WARN: :: org.hamcrest#hamcrest-core;1.1:
> java.nio.channels.OverlappingFileLockException at
> sun.nio.ch.SharedFileLockTable.checkList(FileLockTable.java:255)
> [ivy:resolve] WARN: :: org.glassfish#javax.ejb;3.1:
> java.nio.channels.OverlappingFileLockException at
> sun.nio.ch.SharedFileLockTable.checkList(FileLockTable.java:255)
> [ivy:resolve] WARN: :: org.jboss.weld.se#weld-se-core;1.1.10.Final:
> java.nio.channels.OverlappingFileLockException at
> sun.nio.ch.SharedFileLockTable.checkList(FileLockTable.java:255)
> {code}
> The reason is probably related to our use of the {{<parallel>}} and
> {{<antcallback>}} tasks. The documentation of the {{antcallback}} task
> is here: http://ant-contrib.sourceforge.net/tasks/tasks/antcallback_task.html
> {code}
> <parallel threadcount="${tests.maxThreads}">
> <antcallback target="testsomething" return="tests.failed"/>
> <antcallback target="testsomeother" return="tests.failed"/>
> <antcallback target="testsomemore" return="tests.failed"/>
> </parallel>
> {code}
> All the testxxx targets perform a resolve before running some junit tests in
> a separate vm. These resolve calls appear to cause the
> {{OverlappingFileLockException}}.
