Description bht 2005-01-14 20:41:49 UTC

In my configuration, it looks like it is not
possible to open any Java source file in the editor.

I downloaded the current Q-build and ran it over
my existing NetBeans 4.0 user dir. So I switched
back to 4.0 because I can't use 4.1.

Comment 1 Jan Lahoda 2005-01-14 20:58:13 UTC

Seems like java module problem to me.

Comment 2 ehucka 2005-01-17 10:12:28 UTC

It could be problem with running 4.1 on 4.0 userdir. If you start 4.1
at first time it should find 4.0 userdir at <HOME>/.netbeans and ask
you if you want to import it.
You can try to start IDE on new userdir (or clear the old) and check
if it will fail again.

Comment 3 Martin Matula 2005-01-17 11:07:17 UTC

This seems to be a problem in the classpath API.

Comment 4 Tomas Zezula 2005-01-17 12:55:21 UTC

It is not a problem of ClassPath. The ClassPath was constructed with
ClassPathImplementation which violates ClassPath contract. The
getResources () method returns null.

Who constructed such a ClassPath? ECRequest?

To Reporter: You should add more details. Is the file from project or
is it non project file? If it is a project file, what type of project
is it (j2seproject, project from ant script, web, j2ee)?

I will add an assertion into ClassPath to throw AssertionError rather
than NPE.
