I'm trying to run a TeamCity (default) build agent with 32-bit java on ubuntu 64-bit, I have created a [TeamCity]/bin/setenv.sh what contains:

JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun

That works fine running the server with 32-bit jre, but not for the agent: I've tried these lines in [buildAgent]/conf/buildAgent.properties

JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun
JRE_HOME=/usr/lib/jvm/ia32-java-6-sun/jre

and also a '[buildAgent]/jre' link

[buildAgent]/jre -> /usr/lib/jvm/ia32-java-6-sun/jre/

when I do a '[TeamCity]/bin/runAll.sh start' I get this:

Using CATALINA_BASE:   /srv/TeamCity
Using CATALINA_HOME:   /srv/TeamCity
Using CATALINA_TMPDIR: /srv/TeamCity/temp
Using JRE_HOME:        /usr/lib/jvm/ia32-java-6-sun
Using CLASSPATH:       /srv/TeamCity/bin/bootstrap.jar:/srv/TeamCity/bin/tomcat-juli.jar
Starting TeamCity build agent...
Java executable is found in '/usr/bin/..'.
Starting TeamCity Build Agent Launcher...
Agent home directory is /srv/TeamCity/buildAgent
Current Java runtime version is 1.6
Lock file: /srv/TeamCity/buildAgent/logs/buildAgent.properties.lock
Using no lock
Done [16436], see log at ../logs/teamcity-agent.log

As you can see from the output, the server is using 32-bit jdk, but the build agent is running the java found in '/usr/bin' (which is 64-bit in my case).

Closer inspection of the '[buildAgent]/bin/findJava.sh', it looks like the script runs a 'which java' and finds the default system java before it even tries any of the supplied args/folders. I think it should find '[buildAgent]/jre' before the system java.

Whats the correct way to specify the java version to use for a build agent, which may be a different version than the server?

Should I just modify findJava.sh to check its arguments before checking the system path for java?
