Description Roman Strobl 2005-07-22 11:47:47 UTC 
[NetBeans 200507211800; WinXP; JDK 1.5.0_04]

I am writing a small plug-in and I am getting attached NPE all the time when
editing sources. I am using apisupport.project [1.8 200507211800]. The exception
occurs for instance if I click into imports of the ZipProject.java class -
project attached, too.

java.lang.NullPointerException

NPE
Comment 2 Martin Krauskopf 2005-07-22 11:54:28 UTC 
Strange. I've tested this by simple test which goes through all modules in the
platform and it works. I'll take a look at it.

FYI, I didn't get any such exception before, it started today once I downloaded
apisupport from UC.
Comment 5 Martin Krauskopf 2005-07-22 12:30:41 UTC 
Fixing NPE.

Checking in queries/GlobalJavadocForBinaryImpl.java; 1.1 --> 1.2

Romane could you try to reproduce the bug with the patch and with passing the
following switch to your NB instance, just for curiosity. You should see in a
console line(s) like:

'Cannot found FileObject for " + binaryRootF + "(" + binaryRoot + ")"'

with binaryRoot(F) substituted. Thanks.

Here is the switch
-J-Dorg.netbeans.modules.apisupport.project=0
Comment 6 Roman Strobl 2005-07-25 21:22:30 UTC 
It works now ok on both computers where I've tried it - no exceptions are
thrown. However I do not get any new messages in the console. Verified.
