#82 NullPointerException with RDi 9.6.0.7

[Samuel Hansen]

Confirmed to fail on 3.6.0r on RDi 9.6.0.7 but still works correctly on RDi 9.6.0.6. Both message file search and source file search fail with a null pointer exception. Console log error attached.

Sorry, but I cannot reproduce the problem. I also cannot understand why there is a NullPointerException (NPE), because technically that should be impossible.

The NPE happens in class com.ibm.as400.data.PcmlDocRoot, statement 52. That is:

    public PcmlNode getElement(String qName) 
    {
        return (PcmlNode) m_hash.get(qName);
    }

The only way to get a NPE there is when m_hash is null. But actually m_hash cannot be null, because it is initialized in the constructor of the class:

    PcmlDocRoot() 
    {
        m_hash = new Hashtable();
    }

The source code of PcmlDocRoot can be found here:

https://sourceforge.net/p/jt400/svn/3324/tree/trunk/src/com/ibm/as400/data/PcmlDocRoot.java#l52

Can you install RDi a second time (parallel to your existing installation) and try the search again?

Though I do not think that it is an iSphere plug-in or library issue, please also check that you use the right library.

The NPE happens before the program call, so actually it cannot be a library issue.

I am lost. Maybe '-clean' helps to get things fixed.

New instance of RDi with iSphere works as expected.

With original instance I attempted -clean with same results. Attempted new workspace and removing all plugins except base RDi and iSphere. Different error now, attached.

Samuel,

since a new instance of RDi/iSphere works fine and since nobody else reported a similar problem I suggest to close the ticket. It seems as if something went wrong with the update on 9.6.0.7.

Last but not least the relevant iSphere classes have not been changed for a long time.

I do not know what to check further.

Thomas.

Thanks Tom, I'll have our development team reinstall RDi. We can close it out.
