We have some changes coming down the pipe that should reduce memory usage; in the meantime, you can increase the maximim heap of the editor by editing the DartEditor.ini file. The line you want to change is the -Xmx line.

You can find the DartEditor.ini file in the same directory as the executable. On the Mac, you have to right click the application and choose 'Show Package Contents'. The ini file is a few directories down in Contents/MacOS.

From feedback: I keep getting "java.lang.OutOfMemoryError: Java heap space" when I try to compile my simple dart project to "optimized javascript." I would copy+paste the stack trace, but its very large.

The dartc team just landed some tree-shaking changes that will make the generated javascript much smaller. When this new output gets fed into the jscompiler (the --optimize step), we should no longer see the out of memory problems.

Our next integration builds (and the current continuous build) will pick up these changes. Please re-open this if you still see the problem!

Added Fixed label.
