T5 NPE on service realization

Hi all,

I was just curious if anyone has had weird NullPointerExceptions on service
realization.  I am getting this NPE when using this service for the first
time after startup:

if (hu == null)
	throw new RuntimeException("bad"); //debug and system.out show this as a
proxied service
if (con == null)
	throw new RuntimeException("bad");
if (statement == null)
	throw new RuntimeException("bad");
if (params == null)
	throw new RuntimeException("bad");

return hu.getInsertKey(con, statement, params); //NPE thrown on this line

I really am at a loss because I can see the object as not null plain as day
and it makes it past the null checks.  Anyone have an idea what might be
causing it?

Hi,

please share some more of the code + stack trace, without those further
speculation is nearly impossible.
