I can start idea with xmx786m. But if I set the value to anything larger, I get the below error.
This is on Windows XP-64 using the jdk-1.6.04 included with idea.
I have had a similar with eclipse, where only the eclipse 3.4-M4 for 64bit allows the use of more than xmx786m so this is probably not just an idea issue.
Anyone else using windows-64 seeing this problem?
