Showing intellij command line arguments

I have a java app that loads an enormous data set into memory (don't ask - it's messy). This app runs fine in the IntelliJ debugger but gives OOM (out of memory errors) when I try to run it as a compiled .jar file.

How would I find out the params that IntelliJ is using to run it? Looking at the process list didn't reveal anything promising.

The first line in the Run toolwindow in IntelliJ IDEA shows the exact command line used to run the program, including all VM options.

You can simply do something like this:

java -jar -Xmx2048m myJar.jar

The xmx flag should allow you to add more memory for your jar to work with. You can just up this until it works.
