I just updated to the newly-released Oracle Studio 12.5-beta in the hope of getting around a long-standing problem with the "collect" utility running with Oracle Java. (This also happens with 12.4 and with previous versions, and it happens with Java 8. It reproduces fairly easily, but requires a really busy server.) (No, I can't release anything useful about the source code or even the Java byte codes; sorry. I hope the stack trace is enough or that I can gather more information somehow.)
