We are observing a hotspot VM crash with EXCEPTION_ILLEGAL_INSTRUCTION. The dump generated by the VM is at the bottom of this Description section.

This crash occurs as a result of attempting to obtain random bits from a SecureRandom instance which has not been explicitly seeded.

In other words, the following sequence triggers the crash:

        SecureRandom rng = new SecureRandom();
        long seed = rng.nextLong();

If the code is modified to set a seed first, the crash is not observed. So the following sequence of events does NOT crash:

        SecureRandom rng = new SecureRandom();
        rng.setSeed(1L);
        long seed = rng.nextLong();

(While our code used nextLong(), any retrieval of random bits will cause the crash as well, e.g. nextInt()).

While we have no information whether this is truly correlated, it is worth noting that this has only ever been observed on an AMD processor PC.

Furthermore, if the VM is run with -Xdebug option, the crash will not occur. So it seems there is an interaction between the hotspot compilation(??) and the secure random internal seeding, perhaps only on AMD processors(?) which triggers the fault.

Unfortunately I have not been able to come up with any small test case to demonstrate this behavior. If I take the above lines of code and wrap them in a main(), it will work just fine.

The above sequence of operations occurs during the server startup of the SunONE Application Server 7 and there is where this crash is observed. It may be that triggering the bug requires a large number of classes being loaded. The SecureRandom use in the AS7 occurs early in the startup process of the server.

The AS7 beta is available and could be used as a testcase to demonstrate this bug.
