-------------------------------------
Summary: OverlappingFileLockException when using artifact-lock-nio
Key: IVY-1454
URL: https://issues.apache.org/jira/browse/IVY-1454
Project: Ivy
Issue Type: Bug
Components: Core
Affects Versions: 2.4.0
Environment: Debian Linux (Wheezy)
Oracle Java 1.7.0+update45,
ivy_2.4.0.alpha_20131214174343.jar downloaded from
https://builds.apache.org/job/Ivy/446/
Reporter: Carsten Pfeiffer
Priority: Minor
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}}.
