Comment 1 Frederic Fusier 2004-09-14 05:07:38 EDT

In order to help us to reproduce the problem, please provide some more information:
 - build you're using
 - does it happen on each method of any class in Package Exlplorer or only on 
   specific ones?
 - if specific ones, then attach class(es) which contain(s) failing method(s)

Comment 2 bernhard schmidt 2004-09-14 05:27:49 EDT

hi

sorry i forgot to provide the conditions, but the problem occured when i am
setting up with the left hand the linux box and with the right hand i worked
on my java project.

Version: 3.0.0
Build id: 200406251208

the problem occurs only when i search references for the method:

	public void setCursor(MultilineTextPosition pos)

hope this helps.

best regards
benny

Comment 3 Frederic Fusier 2004-10-28 07:11:18 EDT

Unfortunately this method seems not to be in Eclipse 3.0 code.
I cannot find MultilineTextPosition class...
If this is a piece of your code, I need a complete example to help me to
reproduce this problem, thanks
Another question, could you have a try with 3.0.1 build and let us know if this
problem also occurs with this build?

Comment 4 Channing Walton 2004-11-01 07:09:29 EST

I've had this problem with I20041013 (3.1.0 stream).

I was searching for declarations of a method in the workspace.

Comment 5 Frederic Fusier 2004-11-01 07:27:01 EST

Which kind of method? A specific one or an existing of rt.jar library or eclipse
plugins?
If this is a specific method (ie. one of your projects in your workspace or your
own librairies...), would it be possible to have a sample example to help us to
reproduce this exception?
Thanks

Comment 6 Markus Keller 2004-11-05 06:36:18 EST

I can reproduce this in 200411042000 in my development workspace by searching
for references to Object#clone() from a jdk1.5.0 rt.jar.

My workspace has compiler compliance level 1.4 and a j9 vm as default jre. I
have several project configured with jdk1.5.0.

However, I could not reproduce it in a fresh workspace so far.

Comment 7 Markus Keller 2004-11-05 06:48:33 EST

Search for declarations of clone() gives the same problem, but only after many
matches have been reported. Reference search fails immediately.

Frederic, please contact me if you want me to debug something with my dev
workspace (where I can reliably reproduce it).

Comment 8 Frederic Fusier 2004-11-05 08:05:06 EST

Thanks Markus for the inputs.
I'll jave a look on them next week and let you know if I need your workspace...

Comment 9 Frederic Fusier 2004-11-09 11:04:40 EST

OK, I got it looking for declaration of clone() using rt.jar 1.5.
Thanks Markus for your efficient help on this :-)

Comment 10 Frederic Fusier 2004-11-09 11:58:14 EST

Here a simple scenario to reproduce this problem:
1) Open a workspace using Sun JRE 1.5.0
2) Set workspace default VM to 1.5.0
3) Create new project and create following class:
    X.java:
	public class X {
		Object foo() throws CloneNotSupportedException {
			return this.clone();
		}
	}
4) select clone method in statement: return this.clone();
5) Search for declaration of this method in Workspace

Then, you get Java Search error dialog:
An internal error occured during: "Java Search".

Comment 11 Frederic Fusier 2004-11-09 16:26:53 EST

Fixed.

It seems that some class file has a source file name without ".java" extension.
Protect qualified name construction from this...

[jdt-core-internal]
Changes done in PossibleMatch#getQualifiedname()
No test case added, just verify that no error occurs while executing comment 10
scenario...
