> We should always use the {{libjvm.so}}, {{jni.h}}, and {{jni_md.h}} under {{JAVA_HOME}}, rather than trying to look for them in system paths. Since we compile with Maven, we know that we'll have a valid {{JAVA_HOME}} at all times. There is no point digging in system paths, and it can lead to host contamination if the user has multiple JVMs installed.
