JNI issue in LzoDecompressor_decompressBytesDirect

[luchsh]

The type of the second parameter of GetStaticObjectField should be 'jclass' instead of 'jobject',
this can be found by specifying jvm option "-Xcheck:jni".

JNIEXPORT jint JNICALL
Java_com_hadoop_compression_lzo_LzoDecompressor_decompressBytesDirect(
	JNIEnv *env, jobject this, jint decompressor
	) {
.....
	// Get members of LzoDecompressor
	clazz = (*env)->GetStaticObjectField(env, this, 
	                                             LzoDecompressor_clazz);
