Memory leak in RichTextEditor

[eclipse-kitalpha-bot]

Yourkit analysis

Steps to reproduce:

• Launch Capella
• Create a new Project
• Close Capella
• Launch Capella with Yourkit
• Open the session (double click on the aird file)
• Expand the semantic model and select "Operational Analysis"
• In the Properties view, activate the first "Description" tab
• Expected: The "rich text" editor is visible.
• Select the project
• Click on the Eclipse menu bar "Project/Close" (this is used to close the session without using contextual menu that causes other memory leaks).
• In Yourkit:
  • Capture a memory snapshot and open it
  • in the "Object explorer" section, filter with "org.polarsys.capella.core.data.oa.impl.OperationalAnalysisImpl"
  • Observed (not expected): You have one OperationalAnalysisImpl object retained by the RichTextEditor (see "yourkit.png").

This is maybe caused by the keyListener added in org.polarsys.capella.core.ui.properties.richtext.CapellaMDERichTextFactory.installKeyListener(MDERichTextWidget) but never removed.
