DefaultCacheManager becomes corrupted after component start Exception
---------------------------------------------------------------------
Key: ISPN-1034
URL: https://issues.jboss.org/browse/ISPN-1034
Project: Infinispan
Issue Type: Bug
Components: Cache Server
Affects Versions: 4.2.1.FINAL
Environment: Linux zeus 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
Reporter: Raman Gupta
Assignee: Manik Surtani
Priority: Minor
If Jgroups cluster startup throws an Exception the CacheManager becomes "corrupted", and a retry to get the cache from the CacheManager fails even with the underlying issue removed.
For example, with the following code:
=============================================================
private Cache initCache(String name)
{
Cache cache;
for(int i = 0; i < 2; i++)
{
try
{
System.out.println(i + " cacheManager.getCache");
cache = cacheManager.getCache(name);
System.out.println(i + " cache.start()");
cache.start();
System.out.println(i + " done");
return cache;
}
catch (Exception e)
{
System.out.println(i + " exception:");
e.printStackTrace(System.out);
try
{
Thread.sleep(5000);
}
catch (InterruptedException e1)
{
// ignore
}
}
}
return null;
}
=============================================================
I can get the following output when JGroups does not start (due to an unrelated issue -- http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7032558):

On the second attempt, the Exception is no longer the same, but rather a NPE in the DefaultCacheManager.
The NPE occurs EVEN WHEN the underlying cause of the first Exception(in my case a network interface that was causing JGroups channel init to fail) has been removed during the sleep time between the attempts, and therefore the program is stuck until a new DefaultCacheManager is created. With a dependency injection approach, creating a new manager for retries is not always feasible or desirable.
