Bug 66439 Copy of Class causes update error in package explorer
RC1 RHEL JDK 1.4.2_02 Motif I have experienced a problem where I copy a java file and paste it into the same package, accepting the default new name (CopyOfClass.java) However, the package view does not list the class, but it does list 2 instances of the last class in the package (note that I am using the hierarchical view). The file is aparently inserted in the correct location, but the name->class mapping is incorrect: clicking on classes that appear before where the new class should be inserted brings up the correct class, but clicking on classes that appear after the inserted class brings up a different class than the one selected. Restarting eclipse causes the problem to go away

int min = 0, max = count - 1;
		while (min <= max) {
			int mid = (min + max) / 2;
			Object data = items[mid].getData();
			int compare = sorter.compare(this, data, element);
			if (compare == 0) {
				
				while (compare == 0) {
					++mid;
					if (mid >= count) {
						break;
					}
					data = items[mid].getData();
					compare = sorter.compare(this, data, element);
				}
				return mid;
			}
			if (compare < 0)
				min = mid + 1;
			else
				max = mid - 1;
		}
		return min;
