InvalidObjectException after source code editing
I'm using JSE8 build number 051011_2
I was editing a java source file in a project (a project I had been working on for a few weeks with no problems) a few days ago and the code I was entering seemed to really confuse the syntax highlighter. I deleted the code. However, I started getting these error message alert boxes popping up every few seconds claiming "Invalid Exception" etc.. Well, I finally had to delete the whole class file and recreate it. The errors stopped popping up over and over again, but now every time I open that project I get a single error alert box that goes away after I click it. Everything works fine (at least I think) from there on. The details of the error are are pasted below. Fortunately, it's not a show stopper, but I'd like to know if this is a known issue and if there is some workaround for it.
javax.jmi.reflect.InvalidObjectException: Object with MOFID 68244FB2-0D56-11DB-9E2F-38B1B7B2AA77:00000000000009E1 no longer exists.
