Sure it is in the hs_err_pid33861.log file you sent to the list on the 10th:

java.lang.ClassLoader$NativeLibrary.load(Ljava/lang/String;)V
java.lang.ClassLoader.loadLibrary0(Ljava/lang/Class;Ljava/io/File;)Z
java.lang.ClassLoader.loadLibrary(Ljava/lang/Class;Ljava/lang/String;Z)V
java.lang.Runtime.load0(Ljava/lang/Class;Ljava/lang/String;)V
java.lang.System.load(Ljava/lang/String;)V
com.sun.jna.Native.loadNativeLibraryFromJar()V

sun.reflect.DelegatingConstructorAccessorImpl.newInstance([Ljava/lang/Object;)Ljava/lang/Object;
java.lang.reflect.Constructor.newInstance([Ljava/lang/Object;)Ljava/lang/Object;
... etc ...

One idea diagnose this it to replace the libjnidispatch.jnilib in
netbeans/platform/modules/ext/jna-3.2.7.jar with your debug version
and then step through the Java_java_lang_ClassLoader_00024NativeLibrary_load
call that crashes.
