Wrong Natives Being Shipped With Nightlies?

I just downloaded the December 12 nightly build and I’m getting the version mismatch error when using the JARs that it bundles

Exception in thread "LWJGL Renderer Thread" java.lang.LinkageError: Version mismatch: jar version is '19', native library version is '22' at org.lwjgl.Sys.<clinit>(Sys.java:105) at com.jme3.system.lwjgl.LwjglAbstractDisplay.run(LwjglAbstractDisplay.java:204) at java.lang.Thread.run(Thread.java:680)

Any thoughts?

Normally not, no. But overwriting old binaries sometimes fails…

Perhaps you have those libraries somewhere else in your PATH?
