Summary: "Could not create the Java virtual machine."

Initial Comment:
I ran a program that caused Java to run out of available memory. DrJava gave me an error message which prompted me to change the available heapspace. I changed it to the highest value on the list. Then I restarted DrJava, and immediately got a message: the title of the window was "Java Virtual Machine Launcher" and the only contents were an error image (white 'X' on red), the text "Could not create the Java virtual machine.", and an "OK" button. When I press "OK" the same error message pops up again, until I've pressed it two or three times. When I try to compile a simple program, I get the DrJava error at the bottom of this page (the really long block of text), and then the Interactions Pane reads "Compilation completed." I compile it a second time, and I get the same "Could not create the Java virtual machine" message. When I try to run the program, I get that message yet again, and after clicking "OK" on each successive window that pops up, the following is displayed in red text on the interactions pane: "JVM failed to start.  Make sure a firewall is not blocking 
inter-process communication.  See the console tab for details."
and on the console:
	java.io.IOException: Unable to run process; class path may need to be adjusted
		at edu.rice.cs.plt.concurrent.ProcessTaskController$1.run(ProcessTaskController.java:157)
		at java.lang.Thread.run(Unknown Source)

My OS is Windows Vista
JDK 6.0_7
DrJava version: drjava-stable-20090821-r5004
Note: I had never seen any of these error messages (other than running out of memory) before I made the change described above.

DrJava error message:
