IMPALA-12273 Fix possible memory corruption of premature release of objects
returned by native methods
In the Jni Native method, there was an erroneous usage of JniLocalFrame.
The JniLocalFrame mistakenly released the reference to the returned object
during its destruction,
causing the object to be reclaimed during high-concurrency garbage collection.
The solution is to remove the JniLocalFrame-related code, since the native
method does not create
a local frame in JniEnv.
Testing: During stress testing, there have been no further occurrences of
memory corruption.
