Bug 26641 No option to disable "Assignment ... has no effect"
2.1 M3 I am missing an option to disable the compiler warning upon assigning a variable to itself...
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/CompilerConfigurationBlock.java
String[] filters= getTokens(text);
		for (int i= 0; i < filters.length; i++) {
			String fileName= filters[i].replace('*', 'x');
			int resourceType= IResource.FILE;
			int lastCharacter= fileName.length() - 1;
			if (lastCharacter >= 0 && fileName.charAt(lastCharacter) == '/') {
				fileName= fileName.substring(0, lastCharacter);
				resourceType= IResource.FOLDER;
			}
			IStatus status= workspace.validateName(fileName, resourceType);
			if (status.matches(IStatus.ERROR)) {
				String message= JavaUIMessages.getFormattedString("CompilerConfigurationBlock.filter.invalidsegment.error", status.getMessage()); 
				return new StatusInfo(IStatus.ERROR, message);
			}
		}
		return new StatusInfo();
	}
	
	private IStatus validateTaskTags() {
		return new StatusInfo();
	}	
	
	private String[] getTokens(String text) {
		StringTokenizer tok= new StringTokenizer(text, ","); 
		int nTokens= tok.countTokens();
		String[] res= new String[nTokens];
		for (int i= 0; i < res.length; i++) {
			res[i]= tok.nextToken();
		}
		return res;
