[Mike Cico]

I’ve been trying to reverse engineer our app, and am getting an NPE (in the root cause exception). I’ve tried just selecting individual files, but I always get the same error.

I recenly upgraded to 4.1.1, started the IDE with a -clean switch as is usually suggested, and still get this error.

We don’t use JSE 5.0 language features in this code.

mcico,
Could you send us the smallest subset of files that shows this problem? If you cannot could you try to create general outline of the file so that we can replicate the issue.
(FYI: Email support@genuitec.com w/ ATTN: Kapil as subj)

[Mike Cico]

I just emailed you a file. It is basically just an interface of constants.

[Kapil Kapre]

Michael,
I recieved your file, but wasnt able to replicate. Q: Is the java file part of a java project? If not , try creating a java project and dumping the files in a source folder.

[Mike Cico]

It is part of a Java project, in fact I had created an earlier repository and was initially attempting to update it. I then created a new one and tried to populate that, but I get the same error.

[Kapil Kapre]

Thats strange, It should work right away. Could you try with a new workspace and see if that sorts it out? ( I assume you know anyway but just to get it out of the way, the java file(s) should be a in an eclipse source folder)

[brownmik]

FYI, I’m getting the exact same NPE error, right down to the line number (ModalContext.java:357).

Mike Brown

[brownmik]

Hmm – was just messing around, and it seems to work fine if the source folder containing the Java file is not linked. If I use it with my linked source folders, it fails every time.

FYI,

Mike

[Kapil Kapre]

Mike.
Could you post all the information we request [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]here[/URL].
Also can you try the solution I suggested in the earlier post.

Thanks for following up. I’ll file this as a bug.

[Mike Cico]

I didn’t get a chance to try a different workspace, but I can confirm that my src folder is a linked folder, like the “other” Mike’s seems to be.

I tried with another project that does not use a linked folder, and that worked fine, so it seems to be the same issue.
