Summary: Document.selectNodes() returning NULL Objects

Initial Comment:
Our application uses Dom4j 1.4 for Unmarshalling XMLs into Java objects. Until 
recently, we used Sun JVM for Java 1.4.2_06. But since we moved to JRockIt JVM 
R26-4.0 for Java 1.5.0_06, we are facing this problem with Dom4j 1.4.

We unmarshall the objects while booting the application and store them in 
memory (this is because, the objects are accessed very frequently). Initially, 
everything will be fine and all the unmarshalled Document objects will be 
behaving perfectly. But, some time later, while the application is still 
running, we start exepriencing problem with these Document objects, which are 
stored in memory. The selectNodes() method will return a list will NULLs. Which 
results in NullPointerException in the execution. 

Please let me know a similar cases have occured before and upgrading to Dom4j 
1.6.1 will solve this problem.

Thanks.
