Description
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:
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:
