My Eclipse RCP project stopped running and i havent changed anything. I have two run configurations, one is .product and another one is application (both had run before problem occured).
When i try to run .product configuration, build is terminated without any log in console (i tried to run debugger but it is terminated somewhere inside native code).
When i try to run .application configuration, there is a lot of errors in console:

The exception from first error log is thrown here (but it is not the LinkageError, just Exception):
try {
result = classInstance.newInstance();
} catch (Exception e) {
throwException(NLS.bind(RegistryMessages.plugin_instantiateClassError, contributingBundle.getSymbolicName(), className), e);
} catch (LinkageError e1) {
I tried to remove: .metadata.plugins .metadata.plugins\org.eclipse.e4.workbench\workingsets.xml
but the problem still exists
EDIT: Problem is resolved. I started application with clear flag (Run Configuration->Main(bookmark)->Workspace Data (Area)->Clear (Flag) and errors disappeared)
