When typing in /playsound entity.cat.purreow jukebox (@p) 01000, it crashes on 1.9 server.

When on a server, playing command /playsound entity.cat.purreow jukebox 01000 crashes the client side minecraft with an error (see attachment), but the server doesn't crash. Instead, (on console) pops up with this error: [08:13:32] Netty Server IO #1/ERROR: java.lang.NullPointerException
[08:13:32] [Server thread/INFO]: 01000 lost connection: TextComponent{text='Disconnected', siblings=[], style=Style{hasParent=false, color=null, bold=null, italic=null, underlined=null, obfuscated=null, clickEvent=null, hoverEvent=null, insertion=null}}
[08:13:32] [Server thread/INFO]: 01000 left the game

On creating a world, (aka client side), I can play it fine.
