I don't know that it's fair to compare communities based upon intelligence. Though not a Java programmer myself, I work with J2EE programmers and they're as mixed a bag as the Python hackers in the sysadmin group. While I would choose LAMP over J2EE any day where the choice is available, it would be due to the community strictly from a technology forecast POV. The issues with Java as a community stem from any combination of things, from a slow evolution of the language and JDK, to Oracle's handling of the community and assets. OpenJDK is making that a little less worrisome, but as far as infrastructure goes, I would say LAMP (P: Perl/Python/PHP) offers the more reasons to choose it.
