(In reply to comment #1) > investigating Side effect of bug 208541 correction. This bug should be fixed by fixing bug 213283, though not a real dup.
Fixed by implementing the fix for bug 213283 (released in HEAD for 3.4M5)
Exact steps to reproduce are: 1. Create a cu with the following content: ------------------------------------------ package test1; public class E1 { public int field; }------------------------------------------ Note the last closing brace must be the last character of the file. 2. Put text cursor on line 5 column 1 3. Shift+DownArrow 4. Ctrl+Shift+F Observe: You get an error dialog. The NullPointerException is in the .log file This error doesn't occur with 3.4M5. Verified for 3.4M5 using I20080205-0010
