java - GCHelper raising exception -

i writing programme (called enchanting, allow kids programme lego mindstorms nxt robots more easily) has front-end (based on scratch, , written in squeak smalltalk) , back-end (written in java, using lejos nxj framework). users drag , drop tiles create code; converted java source file , compiled.

i have included 32-bit apache harmony jdk, because lejos framework requires 32-bit jdk, , because redistribute despite lejos offering re-implementation of java on embedded computer. things work fine under windows xp, , under windows 7 starter, both of 32-bit oses.

on windows 7 (non-starter, 64-bit), backend fails. i've determined harmony.

here simplest command produces failure, java -version, , output thereof (with locale set greek -- don't worry, of output english):
