Looks like the root of my issue is here: /usr/lib/jvm/java/include/jni.h:27:20: jni_md.h: No such file or directory The referenced file is located here: /usr/lib/jvm/java/include/linux/jni_md.h And: [buildmeister at segw include]$ rpm -qf /usr/lib/jvm/java/include/jni.h j2sdk-1.4.2_10-fcs So this looks like Sun's bug.
