+Subject: [PATCH] Try to load lz4-java from java.library.path, then fallback to bundled
+
+Use system-provided lz4-java, if it's available on the java.library.path
+(the default location where Java looks for native libraries), and fallback
+to bundled binary if it's not. This allows user to use lz4 java even
+on systems that are not directly supported, like Linux with musl libc,
+uClibc etc.
