alt Hacker NewsI certainly already experienced crashes due to JIT miscompilations, even though it was a while back, on Websphere with IBM Java implementation.
Also it is almost impossible to guarantee two runs of an application will trigger the same machine code output, unless the JIT is either very dumb on its heuristics and PGO analysis, or one got lucky enough to reproduce the same computation environment.

As long as the JIT is working properly, it shouldn't matter: the code should always run "as if" it was being run on an interpreter. That is, the JIT is nothing more than a speed optimization; even if you disable the JIT, the result should still be the same.
