java.lang.NoSuchFieldError: SIZE thrown while loading gnu.io.RXTXCommDriver #120

Hey guys,

I'm using nrjavaserial with netbeans and everything works fine, as long I start my code from netbeans. I've tested two ways for the natives directory 1: I've added it to the classes directory and 2: just added it as source. Both works like a charm.

But when I load the jar with java.exe, I receive the exception above. Advapi32Util.registryGetValues is throwing it.

This is caused by an incompatibility between the jna.jar and the jna-platform.jar you are using. The JNA folks removed Pointer.SIZE in JNA 5.0 (current is 5.1) and replaced it with Native.POINTER_SIZE for commonality of classes in JNA. That said, since NRJavaSerial uses jna-platform for its Windows support, be sure your jna.jar and jna-properties.jar are the same version.
