Description Jakub Markos 2012-11-28 15:08:45 UTC

Following tests
https://svn.devel.redhat.com/repos/jboss-qa/jdg/jdg-functional-tests/trunk/invm/write-behind-store/src/test/java/com/jboss/datagrid/test/asyncstore/AsyncFileCacheStoreWithEvictionTest.java
https://svn.devel.redhat.com/repos/jboss-qa/jdg/jdg-functional-tests/trunk/invm/write-behind-store/src/test/java/com/jboss/datagrid/test/asyncstore/AsyncFileCacheStoreWithoutEvictionTest.java
are failing using Tomcat 7.0.33.

The failure of the first test can be found here (the errors are the same for both tests):

Comment 1 Jakub Markos 2012-11-28 15:22:18 UTC

I've tried running the tests with older infinispan versions, and they work with Infinispan 5.2.0.Beta1, but not with 5.2.0.Beta2.

Comment 2 Tristan Tarrant 2012-11-28 15:32:15 UTC

Possibly related to https://bugzilla.redhat.com/show_bug.cgi?id=880528 ?

Comment 3 Radim Vansa 2012-11-29 09:49:49 UTC

Tristan: In 880528 the race is between object construction and start method call while here the race is between inject and start method calls or the inject method contains invalid arguments. So, the similarity is in the buggy component but it is not the same bug.

Comment 4 Tristan Tarrant 2012-12-05 13:07:53 UTC

Let me paste the jenkins log here:

Comment 6 Tristan Tarrant 2013-02-15 15:05:41 UTC

The test creates a cache, extracts the store component, and then stops and restarts the cache. It then tries to reuse the store component, which at this point is invalid.
To fix the test, just move the extraction of the store component after the cache restart.
