Description

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.
