Mike, I am running JBoss 4.2 which does not like jdk1.6.0, yet. And I setenv JAVA_HOME to /usr/local/jdk1.5.0. That is why I am saying that we'd better include JAVA_HOME in eclipse.in. When all java stuff supports jdk1.6.0 it will not be necessary, but for a being, I feel that it will be better to force it to use jdk1.6.0 in startup file.
