Description
See http://www.netbeans.org/issues/show_bug.cgi?id=74362

It seems to be caused by that do-while loop never exits in the BufferedInputStream#read1. Since the same code works on 1.5_06 and 1.6.0-beta59g I'm inclined to think that it might be an issue in the latest builds of the Mustang (issue exists at least on 1.6.0-beta2-b78 and 1.6.0-beta2-b79).
