Description
In setNativeEnvironmentVariable() native implementation, Strings are converted to C from Java, but not released

Expected behavior
Every call to GetStringUTFChars() must be finalized with a corresponding call to ReleaseStringUTFChars().

Current behavior
There seems to be no noticeable effect right now, but future hardening of the JVM or NDK may cause a problem here. Or, calling this method thousands and thousands of times could cause some visible memory leak.
