Exception when opening an XML file using eclipse (Oxygen 9)

[effjay]

Hello,

I have installed the new version into Eclipse and have sometimes problems using it. Some XML files throw exceptions... this is the exception:

Hello,

Some XML files throw exceptions

I opened an XML file from a SVN repository by a double click on the file in the SVN Repository view but I did not get the error. How do I reproduce the error? What do you mean by "some XML files"? Do you get the error when you try to open the same file from the SVN working copy?


Regards,
Sorin

[effjay]

It seems I can open the file when I check it out first. I tried to open another file from the SVN view and got another exception.

I tried to open another file from the SVN view and got another exception.

Yes, I get the same error. We fixed it and the fix will be included in the next build of the oXygen plugin which will allow opening remote files from a SVN server using the Subclipse plugin.

Sorin

[effjay]

Great! Thanks. Does this also apply to the first exception? (NoClassDefFound?)

[sorin_ristache]

I cannot reproduce that. How can I reproduce it?


Regards,
Sorin

[effjay]

Ok, I don't know... it appears rather random to me. Yesterday I had the NCDF error even without SVN usage, so I guess its not connected to the NPE. I reinstalled Oxygen and the problem went away. Today I got the problem once through the SVN view, but I don't get it any more now.

I keep on working as usual, and as soon as I see the exception again and find a pattern, I can post the info here.

Thanks for support so far! Please also keep an eye open for NoClassDefFounds, maybe it happens elsewhere too.

regards
Daniel

[sorin_ristache]

Please also keep an eye open for NoClassDefFounds, maybe it happens elsewhere too.

It seems an Eclipse thread concurrency issue. We will let you know when we will get the NoClassDefFound error.


Regards,
Sorin

[effjay]

I just got the NCDF exception again. It does not seem to depend on the kind of XML file, as I haven't yet opened that kind of file since the upgrade to 9.

I restarted Eclipse and could then successfully open the same file. I did have to restart - if it doesn't open the file once during one "Eclipse-session" it won't ever until a restart of Eclipse.

Sounds like ClassLoader-issue.... Next restart the Classloading worked and all was fine.

I wish you good luck hunting that one down.

Regards,
Daniel

[sorin_ristache]

What is the action that you execute when you try to open a file and you get the NoClassDefFoundError? Do you double click on a file in the SVN Repository view of the Subclipse plugin? This is what you seem to do from the stack trace that you posted.


Regards,
Sorin

[effjay]

I got the same exception, but this time I did not click in the SVN view. I used the project explorer view in eclipse to open the file. If I get the exception again I post an updated stacktrace.

Regards
Daniel

[sorin_ristache]

What is your platform? Is it Windows XP? I do not get the error on Windows XP when I open XML files, XSL files, SVG files, etc from the SVN Repository view or from the Explorer view in the XML Editor of the oXygen plugin.


Regards,
Sorin

[effjay]

Yes, Windows XP. It only happens sometimes, most of the time all is fine. Especially when I want the error to happen, then it won't.

Regards
Daniel

[effjay]

I finally managed to produce a stacktrace for you.

The visual result was that the XML editor window just did not open. I saw the tab head with title "Oxygen XML Editor" (where normally the filename would be) but without contents. I observed some heavy CPU usage when I try to open the file, as well when I try to close the not-really-opened editor view. Now I am going to restart eclipse and see what happens

[effjay]

After the restart I can open the file (using the same way as before: through the "Open Resource" dialog) just fine.

[sorin_ristache]

That confirms it is a thread concurrency issue. We will try to find out what is wrong.


Thank you for the stacktrace,
Sorin
