Creating an new abdera instance failed by using java 1.6.0 openjdk

[H8H]

Hi!

I'm writing some code for IBM and for this purpose i use the java 1.6.0
ibm jre, everything works fine. If i switch (or the user) the engine to
java 1.6.0 openjdk abdera throws an NullPointerException by creating its
instance.

Abdera abdera = new Abdera();
---> Throws NullPointerExc:
