Great news, the issue is fixed.

When I ran the installation in debug mode by exporting LAX_DEBUG=true

I found the following error:

checking: "1.6.0_11" against "JRE_J2": failed (wrong version)

• Using VM:............................. /usr/lib/jvm/jre-1.4.2-gcj/bin/java

Then I changed the JAVA_HOME to JAVA_HOME/JRE and updated the PATH to have JAVA_HOME/jre/bin fist in the path the installation worked.

Thanks for your help.
