Problem with JCS and IBM JVM (1.4.1)

[Scott Jarvi]

Hi,
We are using JCS and our applications are deployed on Websphere 5.1, which 
is using 1.4.1 of the IBM JDK.  When calling the remove() method, I get the 
following NullPointer:

at 
org.apache.jcs.engine.memory.lru.LRUMemoryCache.removeNode(LRUMemoryCache.java:385)
	at 
org.apache.jcs.engine.memory.lru.LRUMemoryCache.remove(LRUMemoryCache.java:240)
	at 
org.apache.jcs.engine.control.CompositeCache.remove(CompositeCache.java:727)
	at 
org.apache.jcs.engine.control.CompositeCache.remove(CompositeCache.java:690)
	at org.apache.jcs.access.CacheAccess.remove(CacheAccess.java:373)

I was able to track down what I *think* is a problem in the order of calls.  
In LRUMemoryCache.remove(Serializable), these two lines of code (~line 292):

                       itr.remove();
                       removeNode( ( MemoryElementDescriptor )
                           entry.getValue() );
Same issue with line ~316.
I think these calls should be swapped.  It seems that the IBM implemenation 
of Iterator.remove() behaves slightly differently than Sun's.  Has anyone 
else experienced this problem?

Thanks,
Scott
