Java crash when compiling/uploading blink example with ISP programmer

I have just updated from Arduino 1.0 to 1.0.1 and even the blink example crashed on me. I tried some code of my own too with the same result. See the attached log. It seems the compilation went well but the crash occured when invoking Avrdude. It worked perfectly in Arduino 1.0
I am using the Pololu ISP programmer with the Baby Orangutan 328 target, added as follows:

I guess it is a bug but I don't know where to file it.
