Anu Engineer commented on HADOOP-11526:
---------------------------------------
looks like this test failure is not related to code change:
Code change avoids a memory leak in native code and should not effect this code
path. This is probably a race condition in tests.

> The use of JNI's GetStringUTFChars should be paired with
> ReleaseStringUTFChars or else the utf-8 char* created by Java's JNI
> implementation is leaked. It isn't in Bzip2Decompressor.c:
> https://apache.googlesource.com/hadoop-common/+/refs/heads/trunk/hadoop-common-project/hadoop-common/src/main/native/src/org/apache/hadoop/io/compress/bzip2/Bzip2Decompressor.c#45
> A less error-prone way of handling JNI resources like local references and
> UTF strings is to use a smart pointer like the Apache licensed code in
> Android's ScopedLocalRef and ScopedUtfChars:
> https://android.googlesource.com/platform/libnativehelper/+/jb-mr1.1-dev-plus-aosp/include/nativehelper/ScopedLocalRef.h
