DefaultCacheManager becomes corrupted after component start Exception

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.
