Help crack the Java 1.6 Classfile Verifier

Posted by ryuzaki0 on from the crack-it-break-it-open-jump-on-it dept.

pdoubleya writes "As part of the development of Mustang (Java 1.6), Sun is developing a new, smaller and faster classfile verifier which they want your help in trying to break. As Sun VP Graham Hamilton puts it in his blog entry, "As part of Mustang we will be delivering a whole new classfile verifier implementation based on an entirely new verification approach. The classfile verifier is the very heart of the whole Java sandbox model, so replacing both the implementation and the basic verification model is a Really Big Deal.... The new verifier is faster and smaller than the classic verifier, but at the same time it doesn't have the ten years of reassuring shakedown history that we have with the classic verifier." You can read about the new verifier on Gilad Bracha's blog, and join the new Crack the Verifier initiative to if you can break it. Read all about the Crack the Verifier - Challenge."

    I never got the joy of multiple inheritance, anyways.

    It depends on what you mean by "slow." If you're talking about long running processes, then no, it isn't slow at all; in fact, it is quite fast. If you're talking about short-running processes, then the JVM startup time overshadows any commendable performance.

    Yeah, it is a shame, if only Sun would do something like writing a new faster classfile verifier.

    I believe the place that Java users discuss their religion (and the evils of that new satanic cult C#/.NET that is taking our jobs and women) is comp.lang.java.advocacy

    Pardon my ignorance, but isn't this a violation of the anti cracking clauses of the DCMA?

    Yeah, the day that happens is the day Microsoft puts symlinks into NTFS.
