We are trying to valid a memory.
During a test I got a null pointer exception. I am not sure why.
The memory could be corrupt.
here is the stack trace:
Caused by: java.lang.NullPointerException

    John, Chances are if this is coming from the corrupt memory on nash, then there is an atom that don't exist. I will put in code to protect against this error.

    Yea, I saw the stack trace and suggested that John send a tender. I thought that BaseCategoryValue.equals() may not be following the full Java equals contract: http://java.sun.com/javase/6/docs/api/java/lang/Object.html#equals(.... Of course, a little more info on how our memory may be messed up may be useful.

    Thx
    Harry

    Maybe at the 10:00 meeting I can get more background on this issue.
    Thanks,
    Jim
