Hi,
I was just working for a simple Sudoku Solver and I had to change a byte matrix 
into an array of Vector so I made the following statemente change:

private byte[][] matrix  --->  private Vector<byte>[] matrix

As soon as background code analysis scanned the resulting erroneous definition 
caused by the previous assignement the IDE crashed reporting an "Assertion 
Error" and from that moment I can't open that source code anymore without 
running into that error.

I send you the original (working) java source code, the changed one (not 
working) and the message log generated by the IDE; I hope that it could help in 
solving this issue.

* best regards *
