[BLUEJ-1004] Errors status label in the Java editor may casues confusion

E.g. {quote}private int count = 0a;{quote} states 2 errors (not one) and when navigation through the errors, the message doesn’t change. You need to move the cursor till the end of the line to see the next message, which is not that helpful.
