ArtifactLockStrategyTest.testConcurrentResolve failure
I got this when running ant test:
<testcase classname="org.apache.ivy.plugins.lock.ArtifactLockStrategyTest" name="testConcurrentResolve" time="16.312">
<failure message="expected:<10> but was:<9>" type="junit.framework.AssertionFailedError">junit.framework
.AssertionFailedError: expected:<10> but was:<9>
at org.apache.ivy.plugins.lock.ArtifactLockStrategyTest.testConcurrentResolve(ArtifactLockStrategyTest.java:72)
</failure>
The second time, I got this :
<testcase classname="org.apache.ivy.plugins.lock.ArtifactLockStrategyTest" name="testConcurrentResolve" time="10.344">
<failure message="expected:<10> but was:<2>" type="junit.framework.AssertionFailedError">junit.framework
.AssertionFailedError: expected:<10> but was:<2>
at org.apache.ivy.plugins.lock.ArtifactLockStrategyTest.testConcurrentResolve(ArtifactLockStrategyTest.java:72)
</failure>
</testcase>
Is it only me?
And of curse, I can't reproduce it in eclipse.
I'm using an ibm jvm 1.5 in both command line and in eclipse.

I tried to test it a few time from the command line with only that test and in those case it works.
It is only when I run all of them that I have the issue.
I suspect it might be triggered by the garbage collector put some load at the wrong moment.
I hope it will be reproducible with tracing enabled.

It maybe due to your environment, including your filesystem, since locking
rely on the filesystem. I've tested with sun jvm 1.5 and 1.6, on windows
Vista, windows XP and linux.
It may also simply be due to a slowness of your box, try to increase the
join time at the end of the test (use 60000 instead of 10000) for instance),
and see if it works. To get more details on what is happenning you can set
debugging to true on the lock strategy in the test:
private CacheManager newCacheManager(IvySettings settings) {
CacheManager cacheManager = new CacheManager(settings, new
File("build/test/cache"));
cacheManager.setLockStrategy(new ArtifactLockStrategy(*true*));
return cacheManager;
}
