Charles Duffy commented on IVY-1454: ------------------------------------ Leaving (unlocked) lock files in the cache is actually correct behavior for flock/fcntl-type locking. This ensures that anyone creating a new lock is doing so against the same inode(s). > 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 > Assignee: Charles Duffy > 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.
