Eclipse version:
Version: 3.8.0
Build id: I20120608-1200

Steps to reproduce the problem:

1. Create new java project in eclipse (Test)
2. RMB on src and create new file named as test.xml
3. Open test.xml in xml editor (RMB on test.xml -> Open With -> XML Editor)
4. Add following content as it is (including line break characters) to the xml file

<!-- This is test xml file -->


5. Change XML editor validation preferences as shown in attached XML_Editor_Prefs.png

6. RMB on test.xml and select Validate option.
7. Open the problems view if it is not already open through "Window -> Show View -> Problems" menu.
8. 3 errors will be shown in problems view.

Now, let us refer the content of xml file by line numbers as bellow:

Line 1: <!-- This is test xml file -->
Line 2:
Line 3: <tag1>test</tag2>

Use case 1:
Delete only Line 3 from xml and save the file.
All 3 errors are still shown in Problems view.

Use case 2:
Now delete Line 2 (Line 3 is already deleted)
All 3 errors are still shown in xml file.

Use case 3:
1. Revert the xml file (Add Line2 and Line back to the xml file) and save it.
2. Selecte Line 2 and Line 3 together
3. Delete selected Line 2 and Line 3 together.
All errors disappeared from problems view.

We are working on Eclipse based application and observing similar behavior there.
Is this a "As Designed" behavior?

Thanks in advance!

It's as designed. Java Projects do not default to having the Validation Builder, which would automate XML file validation as part of the build (you can add it from the project's Properties dialog if you wish). Step 6 manually validated the file contents and updated the Problem markers for the file. You'd need to repeat that to see updates since the XML Editor is doing its job by preserving the original problem markers, and even moving them around if you insert new lines before line 2. When you remove the lines that have markers recorded on them, you're removing the corresponding text annotations, removing the underlying markers when the file is saved. Look into the org.eclipse.ui.texteditor.MarkerAnnotation and the associated MarkerAnnotationModel.
