[groovycbug] using return statements in methods declared with a void return value causes "exception occurred during problem dection"

public class VoidReturnTestCase {

void returnSomething()

}

This causes an "Exception occurred during problem detection" message to appear when the file is saved and every time you hover over the first line of the method.

Additionally a orange marker appears at the top of the file on the first line which contains a useful message but the message marker should appear in the gutter of the first line of the method and should be highlighted better.

I'm not sure if the correct marker should be a round red X instead of orange warning triangle.
