Bug 86579 [content assist] guessing parameters is very slow
Eclipse : 3.1M5a Guessing the parameter values in JDT has gone very slow. I have noticed this since 3.1M4. My settings are : Java Editor Code Assist Advanced [x] fill argument names [x] guess names When I turn-off 'guess' method completion & filing in input-parameter name is faster. The plugin project has about 150 Java files and depends on about 20 plugins (not a large one). What other data I can provide to debug this help?

private Position fPosition;
		/**
		 * @param type
		 * @param document
		 * @param position
		 * @param compilationUnit
		 */
		public PositionBasedJavaContext(TemplateContextType type, IDocument document, Position position, ICompilationUnit compilationUnit) {
			super(type, document, position.getOffset(), position.getLength(), compilationUnit);
			fPosition= position;
		}
		
		/*
		 * @see org.eclipse.jdt.internal.corext.template.java.JavaContext#getStart()
		 */
		public int getStart() {
			return fPosition.getOffset();
		}
		
		/*
		 * @see org.eclipse.jdt.internal.corext.template.java.JavaContext#getEnd()
		 */
		public int getEnd() {
			return fPosition.getOffset() + fPosition.getLength();
		}
