JNI Calls to Native Methods No Longer Work: Possible Versioning Issue ?
843829Dec 8 2009 — edited Dec 9 2009Hello, all. Just a quick question... is it possible that invoking a method in a JNI-compliant DLL from Java 6 will fail if the DLL's source was compiled against the JNI header files from Java 4 or 5 ? I have a DLL with methods that used to be called successfully (and now fail outright and don't even seem to be getting inside the native method), but it seems that the only thing that could have changed in the environment is the installed JRE. Even stranger, I don't get the hs_err* files anymore to indicate that the JVM crashed. Does anyone know why this might happen ? Thanks !
