I downloaded and ran GA and got this exception:

Here is my environment:

I tried changing the com.arjuna.ats.arjuna.recovery.recoveryPort value in jbossjta-properties.xml, but got the same result. The CR2 release works fine on this same box (just now ran it, came up OK).

I do not have any applications deployed and am using the 'default' configuration without any changes or additions.

I tried using the JDK 6 variation - same problem.

I brought up Kubuntu 8.04 in VMWare, it gets the same exception as above. Here is the config and exception:

I just now tried on my laptop; it is running a 32-bit version of Vista and I used the JDK6 variant. Works fine there.

I rebooted my laptop into Ubuntu 8.10 (32-bit) and ran the JDK6 variant. It ran just fine.

So I have two locations where I get the above exception. In both of those locations CR2 runs without issue. What changed in Arjuna between CR2 and GA that could cause this issue?
