User Comments:
jkovalsky: Removed unused import from About.java file in Maven based AnagramGame application, scrolled down which caused unexpected removal of grey background of guarded code in initComponents() method, then closed the file and reopen again by double clicking it which tried to open form editor but only I see is grey panel with "Loading ..." message.

Just for the record, when the same build is launched using JDK 1.8.0_45, this exception is not thrown.

Fixed already by https://hg.netbeans.org/web-main/rev/54be89c42ead
