Description Jan Lahoda 2004-07-10 19:38:24 UTC 
(current sources of java module), JDK1.4.2_04.

During scanning of the classpath, the attached
NullPointerException can be thrown (and shown).
The problem is that if the scanning tries to list
files in a directory, and the user do not have
sufficient rights to list this directory,
File.listFiles may return null. The problems is
that the
org.netbeans.modules.javacore.scanning.FileEntry
is not able to handle null from listFiles.

I propose to fix this by adding a test for null.

This situation (insufficient rights for directory
list) can simply happen if a classpath is guessed
for some files in a Favourites tab, etc.

(I am making it P2 as it breaks some of my tests.)
