> This pattern appears in all the native compressors.
> // Get members of ZlibCompressor
> jobject clazz = (*env)->GetStaticObjectField(env, this,
> ZlibCompressor_clazz);
> The 2nd argument to GetStaticObjectField is supposed to be a jclass, not a
> jobject. Adding the JVM param -Xcheck:jni will cause "FATAL ERROR in native
> method: JNI received a class argument that is not a class" and a core dump
> such as the following.

> Java_org_apache_hadoop_io_compress_zlib_ZlibCompressor_deflateBytesDirect ()
> from /usr/lib/hadoop/lib/native/libhadoop.so.1.0.0
> In addition, that clazz object is only used for synchronization. In the case
> of the native method _deflateBytesDirect, the result is a class wide lock
> used to access the instance field uncompressed_direct_buf. Perhaps using the
> instance as the sync point is more appropriate?
