Memory leaks in release critical code
Description
The ICU4JNI code version 3.4 has multiple occurrences of JNI calls to
GetPrimitiveArrayCritical and ReleasePrimitiveArrayCritical (see
converter/ConverterInterface.c and normalizer/NormalizationInterface.c).
ICU4JNI frequently uses release mode JNI_COMMIT alone, which is a checkpoint
copy back of data to the java array and is not required to release the primitive
array memory storage. On VMs that copy the data this introduces a significant
memory leak.
According to JNI the mode flag for copying back the data and releasing the
memory is mode 0.
(Note that on VMs that do not copy the data, the modes 0 and JNI_COMMIT are
equally meaningless and therefore this leak goes undetected.)
