STS can't run a server.

[Slimy]

STS server was broken I don't now, how. I nothing change in config. Just create new project.

New_configuration [SpringSource tc Server]	
	org.apache.catalina.startup.Bootstrap at localhost:53457	
		Thread [main] (Suspended (exception ClassNotFoundException))	
			URLClassLoader$1.run() line: 202 [local variables unavailable]	
			AccessController.doPrivileged(PrivilegedExceptionAction<T>, AccessControlContext) line: not available [native method]	
			Launcher$AppClassLoader(URLClassLoader).findClass(String) line: 190	
			Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: 307
