Martin Jarvis commented on AMQ-3898:
------------------------------------

I tried the same test on my Ubuntu 10.04 server using 
java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

I got the same error:
