We've tried to run IntelliJ IDEA 4 on 1.5-b45, and found that the
following exception is thrown whenever any button in the gui is
clicked, so the ide is, unfortunately, unusable.

A quick investigation revealed that the exception first appeared
in tiger b24.

The exception:
java.lang.NullPointerException
