How can I debug further into the root cause of a version mismatch with natives?
I'm fiddling with LibGDX applets and creating a shaded uber-jar to get around all the signing nonsense (I strip out all the existing certificates, and then sign my own onto the shaded jar).
When I load up the applet on a page served by a local instance of Tomcat I get the following exception:
This occurred while 'Switching applet'
null
java.lang.reflect.InvocationTargetException
at java.awt.EventQueue.invokeAndWait(EventQueue.java:1272)
at java.awt.EventQueue.invokeAndWait(EventQueue.java:1247)

at java.lang.Thread.run(Thread.java:744)
Caused by: java.lang.LinkageError: Version mismatch: jar version is '25', native library version is '19'
I gather this is because there are Java classes expecting a particular version of a native library, but the native found is older. How can I find where these version numbers are defined, so I can attempt to track down the source of the mismatch?
Here's my Maven (yes, I know, nobody likes Maven) dependency tree. I'm using LibGDX 1.0-SNAPSHOT, which I believe depends on LWJGL 2.9.0. I'm probably missing something, but I can't see any older versions of natives sneaking their way in.

Any help would be much appreciated!
