Broken on java-1.4
and a bug in static method getTestString(int len).
This function generates a character with code point equal or smaller then 0xFFFF, and converts
this into array of chars of size 2(which should be one) and appened it buffer.
So resulting into a a null character tobe inserted into string after a no null character.
Find Patch attached.
