Dear all,

I have been working with Eclipse on an Ubuntu system for the past 8 months without issue. Yesterday, totally out of the blue, Eclipse froze when loading and since then I haven't been able to use any more. The same thing happens every time I try to run it: the splash screens shows up, it displays the progress bar and the "Loading Workbench" message and just stuck there.

Running Eclipse from the command line I get this:

$ /usr/share/eclipse/eclipse
LogFilter.isLoggable threw a non-fatal unchecked exception as follows:
java.lang.NullPointerException

What is going on here? Can I do something else to trace the problem?

Thank you.

Here's the last entry in .log file:

!ENTRY org.eclipse.core.resources 2 10035 2012-05-11 08:05:03.376

Could this be related to the missing svn libraries?

Thank you

I found an old reference to a similar problem at this address. I did as it suggests and removed the workspace\.metadata\.plugins\org.eclipse.core.resources\.root\.indexes but the problem remains.

As I understand this has all to do with the message on the exit with unsaved changes. Is there any procedure to deal with it?

Thank you.

Today I found a recipe that got Eclipse starting up again:

Quote:

cd .metadata/.plugins
mv org.eclipse.core.resources org.eclipse.core.resources.bak
Start eclipse. (It should show an error message or an empty workspace because no project is found.)
Close all open editors tabs.
Exit eclipse.
rm -rf org.eclipse.core.resources (Delete the newly created directory.)
mv org.eclipse.core.resources.bak/ org.eclipse.core.resources (Restore the original directory.)
Start eclipse and start working.


According to the author this is just a partial solution, individual projects in the workspace maybe have been damaged and may have to be removed later on. We'll see.

Thanks everyone for the help.
