Summary: Unexplained NullPointerException
Initial Comment:
I got the following uncaught exception only once from
drjava-20030617-2059, with Windows XP running jdk 1.4.
1_03. I am unable to reproduce this problem, so I don't
know how useful this bug report is. Nonetheless, here it
is:
I started up DrJava, typed in a simple class, didn't save it
(so the filename was still "Untitled"), and clicked Compile
All. I got the following exception from DrJava:
java.lang.NullPointerException
at sun.awt.windows.WInputMethod.
dispatchEvent(Unknown Source)

It appeared that DrJava continued to function well from
here, though I will admit I saw this as an excuse to shut
down DrJava and start over. I cannot seem to make this
happen again, so... hopefully this info is useful.
