Problem while creating a class on eclipse (filter class dialog)

[rob]

Hi,

I am not sure if it's a lombok specific problem but i try explain.

I am using eclipse 3.5 with lombok 0.9.3, when i go to the New - >
Class dialog on eclipse and i try to browse for a superclass i get an
error on the "filter class dialog" when i try to type the name of the
class that i want to extend.

the error:
An internal error occurred during: "Items filtering".
Class file name must end with .class

looking at "Show error Log" i get a lot of these exceptions, i report
the message and the stacktrace:

An update: i have the same problem while using the search reference in
workspace function (ctrl-shift-g) on a class.
The problem is always on the "Items filtering"

Hi fedx,

As far as I know, this is a general Eclipse problem. I and some of my co-workers encountered it without lombok as well. See also http://stackoverflow.com/questions/6816/eclipse-class-file-name-must-end-with-class-exception-in-java-search

At the time, I've tried all suggested solutions, but none of them seemed to work :-(

Hi Roel,

in my case closing and re-opening the project solves the issue, thanks.
