java.lang.IllegalStateException: addWriter(): owner already existed
-------------------------------------------------------------------
Key: JBCACHE-83
URL: http://jira.jboss.com/jira/browse/JBCACHE-83
Project: JBoss Cache
Type: Bug
Versions: 1.2
Reporter: Konstantin Avdeyev
Assigned to: Bela Ban
Exception appears in replicated mode (REPL_ASYNC) and NONE isolation level when
two instances putting the same value to cache.
Test case:
The following test was added to AsyncUnitTestCase (Note: isolation level in
replAsync-service.xml need to be changed to NONE)
public void testAsyncReplSameData() {
while(true){
try {
cache1.put("/a/b/", "c", "d");
cache2.put("/a/b/", "c", "d");
} catch (CacheException e) {
e.printStackTrace();
}
}
}
Test output:
-- [Thread[main,5,main]]: creating cache1
-------------------------------------------------------
GMS: address is grc03:1969
-------------------------------------------------------
-- [Thread[main,5,main]]: creating cache2
-------------------------------------------------------
GMS: address is grc03:1972
-------------------------------------------------------
-- [Thread[main,5,main]]: stopping cache1
-- [Thread[main,5,main]]: stopping cache2
