Dmitry Jemerov - 19 Sep 06 13:40 Each version of IntelliJ IDEA is supported on only one JDK version: the version it's bundled with. Running IntelliJ IDEA with any other JDK version is done at the user's own risk. Adding JDK switching UI would mean that we officially support multiple JDK versions, and would require us to increase our testing effort to cover multiple JDKs. Of course, it's easy to write a third-party plugin to implement this functionality.

Prashant Deva - 19 Sep 06 14:04 Well, instead of the jdk you could allow just switching the 'jvm' through a gui. The jvm are all backward compatible so you could only allow jvm versions which are higher than the supported ones. This could be good in cases when a new revision of a jvm comes out, eg - from jvm 5 update 6 to jvm 5 update 7, thus the new update can be utilized. Also in the case of subpixle anti aliasing support in jvm 6, a lot of people are gonna want to switch to it once the final or rc release is out. It is far convinient to do so using a gui than through editing config files. For example, i cant get beta of idea 6 to run with subpixel aa on jdk 6 even after modifying the config files. had you provided a gui support for this, it would have worked correctly since there would be no chance of errors.

Dmitry Jemerov - 19 Sep 06 14:27 We do not support beta JDK releases. When JDK 6 comes out and a version of IntelliJ IDEA officially running JDK 6 is released (most likely this will be version 6.5), it will support subpixel aa and all other new JDK 6 features as required. This has nothing to do with the availability of GUI for editing the configuration files.
