Bug 102150 RCP splashscreen stays forever in case of error
If a serious error occurs during the startup of an RCP application, like a missing plugin etc. so that the application could not start, the splash screen of the application stays for ever. This happens if the application is started by PDE using the "Run as eclipse application" menu, but the process has been stopped using the "Stop" button. I had to kill the new eclipse.exe process using the windows taskmanager.

nameBuffer.append(" ("); 
			final int parameterizationCount = parameterizations.length;
			for (int i = 0; i < parameterizationCount; i++) {
				final Parameterization parameterization = parameterizations[i];
				nameBuffer.append(parameterization.getParameter().getName());
				nameBuffer.append(": "); 
				try {
					nameBuffer.append(parameterization.getValueName());
				} catch (final ParameterValuesException e) {
					/*
					 * Just let it go for now. If someone complains we can add
					 * more info later.

				if (i + 1 < parameterizationCount) {
					nameBuffer.append(", ");
