QUESTION:
Is the RTC BuildSystemToolkit 32-bit only?

THE DETAILS:
I'm running RedHat Enterprise 5.5

cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.5 (Tikanga)

uname -a
Linux stpls130 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

I installed Sun JDK 1.6:

java -version
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)

I installed the RTC BuildSystemToolkit:

RTC-BuildSystemToolkit-2.0.0.2-Linux.zip

I am able to run a JBE successfully, but when it picks up a build, the JBE encounters a runtime error:

2010-07-22 15:41:34 Found a user request for build definition "Dragon 1.0 - Acceptance".
2010-07-22 15:41:34 Should build occur?
2010-07-22 15:41:34 Yes: Always build a user initiated request.
