Why are you changing the internals of Jaybird without clear
understanding of its inner workings?

RETURN, IF, NULL are not valid Java, what language are you using?

The defaultType is normally not null, it is set to the first plugin
loaded when GDSFactory is loaded by the classloader (normally the
pure-Java plugin IIRC).

It is set when the driver is loaded. Please explain clearly when this
error occurs?

I am not sure what you are saying here.

If they are not initialized, then you are most likely not using Jaybird
correctly. Please describe the actual problem you are having, not what
you think is causing it.

Please provide a SSCE (see http://sscce.org/ ) and say which exact
version of Jaybird you are using, and the problem you are experiencing,
so that we can try to reproduce it.
