This looks like an error because Eclipse is unable to write to the
configuration area. Eclipse needs writable areas for its configuration
as well as for the workspace.

Try launching eclipse with a -configuration parameter set to a writable
directory and see if it makes a difference. Inability to write to the
configuration can have more bad side effects so it's important that it
points to a writable area.

See
http://help.eclipse.org/help33/topic/org.eclipse.platform.do c.user/tasks/running_eclipse.htm

Everything works ok without -configuration parameter.
The problem was caused by changes in plugin directory access rights
part of files was owned by normal user - part by root.
After changing ownership of all files in install dir to root
and setting access rights to rwxr-xr-x everything works fine
