I'm still confused about why people seem so interested in using 1.5 for IDEA runtime. I'm excited to use 1.5 for my own projects, but I just can't get why I should care a lick what JVM IDEA itself uses. Are you guys running 1.5 seeing some tangible benefits? Or is it just the "cool" factor?
The one time I experimented with it I was hoping to see a speed increase. Startup time, however, was exactly the same as with the shipping JRE.
