Groovy Grails Tool Suite too small heap size, but only on Debug

When running Groovy Grails Tool Suite (GGTS) version 3.6.4 (latest as of June 2015), on Windows 7 Home 64bit, I get a "Error occurred during initialization of VM Too small initial heap for new size specified". I have a JAVA_OPTS System Environment variable of "-Xms512m -Xmx512m" I also have that same value inside the GGTS Menu: Run => Debug Configurations... Arguments Tab, VM arguments. This error does not happen when I do a run-app inside GGTS, and the app successfully starts. But, when I do try to run using Debug, with the run-app Debug Configuration, I do get this error. Where else could I possibly set the heap values to make this work in Debug? Any ideas of what else to test, fix, or set to fix this issue?

Could not get GGTS to launch my app, no matter what changes I made to -Xms and -Xmx everywhere I could find to make the change. Kept getting the same error. Finally, I stumbled upon this method of setting up the debug. Step 1, start the app from the console (not within GGTS):

grails -debug run-app

Step 2, in GGTS follow these directions to hook-up to the "grails -debug run-app" you just started (use port 5005 - as displayed in the console window), and when done, click the Debug button at the bottom: Create a Remote Java Application launch

Now, debug launches and I can set and view breakpoints inside GGTS.
