You can write intellij idea plugins with JDK 7 or even JDK 8, but that
plugins will only work with IDEA running on same version of JDK. You
must use same version for IDEA SDK and for IDEA itself. Currently
IDEA and all plugins are compatible with JDK 6, so this is why JDK 6 is
recommended.

At the moment many LTS linux distros has JDK 6 (ubuntu 12.04 LTS,
RedHat/CentOS 6). But ubuntu 14.04 and readhat/centos 7 are here now, so
maybe jdk7 will became recommended version soon.
