I have spent several days running Idea 7.0.3 on the official new 64-bit server JDK 1.6 from Apple.

While it mostly works, and resolves some known UI issues (Spaces), I find the overall experience worse than running under 1.5 (client, 32-bit).

The two main issues I find are:

Bad responsiveness of Idea. There is often a large delay between taking a UI action (clicking, etc) and the application responding.

Periodic lockups. Especially when I have multiple Idea windows open (multiple projects, or a single project and a Diff window), Idea will periodically lock up completely, requiring a Force Quit to stop the application.

Minor issues are:

Much slower startup under 1.6.

A feeling that my entire machine (including other non-java applications) is slower when running under 1.6.

In order to ensure the best possible user experience for Idea users on Mac, I would suggest that you change the JDK version specifier in the Mac bundle's Info.plist file from 1.5+ to 1.5*

One additional (minor) issue that I noticed is that in some dialogs (CVS commit comment) with proportional fonts, the highlighted selection and text layout get slightly out of sync (the highlighted section is shorter than the displayed text, even when everything is selected)

And there is one more thing. I've got several kernel panics right before debug session start. Idea was running under 1.6 and debugging application too.

I too tried out 1.6 and quickly switched back. Main reason for me was performance, things were very slow. I did have a couple of deadlocks as well, I think, and I noticed some font proportion issues. Take a look at the "Create a new Java app from scratch" wizard page, the text describing the facets is all "funny".

Fixed in Selena. We'll allow running Diana on 1.6 for now - we'll see how it goes, and if some problems need fixes from our side we'll try to provide them.
