> 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}}.
