This comes from the JNI (Java Native Interface) spec.

VMs have to ensure that at least 16 local references can be created
upon entering a native method.  If a native method needs more local
references it must call EnsureLocalCapicity() or use
PushLocalFrame()/PopLocalFrame() or delete no longer needed local
references with DeleteLocalRef().  See
http://java.sun.com/j2se/1.4.2/docs/guide/jni/jni-12.html#localrefs

If you're using a Blackdown or Sun JVM you can you use -verbose:jni or
-Xcheck:jni to catch such problems.
