I am trying to invoke a third party API, which internally performs some native calls. I hit the following error and the JVM crash follows.

The classes "SomeClass1" and "SomeClass2" are present in a single jar file. I have set my java class path to use this jar. The point here is, SomeClass1 performs a native method call and throws NoClassDefFoundError in trying to find SomeClass2 (which is in the same jar)

Any hints on how I can debug this ?

java.lang.NoClassDefFoundError: xxx/xxx/xxx/SomeClass2
at xxx.xxx.xxx.xxx.xxx(Native Method)
at xxx.xxx.xxx.xxx.xxx(SomeClass1.java:55)
