Why IDEA must run on the provided JRE?

What OS? On windows, I edit idea.lax to point to another JRE dir, and it starts fine.

P.S.
Part of the problem is how Sun deploys the various JRE versions. There should be a way that
an app can specify what JRE it wants to run with and somehow magically run it with that version,
dort of how Java WebStart works

I have always had a question, why IDEA must live on it's own JRE, is there any tricky? I installed too many JREs in my computer, as many Java based software also bundle one, but for the most of them, I can delete it and point it just to the JRE I installed my self, except IDEA, even if I installed a JRE versioned the same or higher than it's own one, it won't start. This has also bring the Download Size problem to me, 2.5 times than a pure one without JRE bundled. :( :(

Could anyone explain this to me, and better if provide a solution. :)

Thanks,

Oops, my mistake, it does not run. But I agree, it should not care as long as the JRE
is the correct version. Want to file a feature request?

in fact, u can use ur specified jre. u should edit the idea.lax file and point to ur jre, AND, u should specify a command line option to disable idea check the jre version. i can't remember exact the option. u can juse searh the forum and some 1 has posted it.
