Benjamin Mahler commented on MESOS-2414:
----------------------------------------
Sorry for missing the earlier comments in this thread. Vinod and I looked
through the [JNI
documentation|http://docs.oracle.com/javase/7/docs/technotes/guides/jni/spec/functions.html#global_local].
For posterity:

Local References
Local references are valid for the duration of a native method call. They are
freed automatically after the native method returns. Each local reference costs
some amount of Java Virtual Machine resource. Programmers need to make sure
that native methods do not excessively allocate local references. Although
local references are automatically freed after the native method returns to
Java, excessive allocation of local references may cause the VM to run out of
memory during the execution of a native method.
