Hi, The _latest_ TYA JIT compiler release you find on TYA's ftp home: ftp://gonzalez.cyberus.ca/pub/Linux/java/tya11v4.tgz Some notes: This release introduces a new JNI approach. If you have any JNI-trouble report this please and meanwhile disable JNINATIVENEW. If you are runing an newer 2.1.x kernel, it is possible you have to disable EXCEPTIONS_BY_SIGNAL. For some other news and changes look into Changelog and README files. Enjoy, Albrecht
