• XMLMultiPageEditorPart.java:759.

How to reproduce

• Install the XML editors from WTP
  • Update site: http://download.eclipse.org/webtools/repository/latest/

• Open any XML file with the XML Editor

How to debug

You will need a 2nd Eclipse IDE (the "Debugger-IDE") to remotely debug the one where you installed WTP (the "WTP-IDE")

• Add the following lines to the eclipse.ini of the WTP-IDE

-Xdebug
-Xrunjdwp:server=y,transport=dt_socket,address=8211,suspend=n
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9899
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

• Start the WTP-IDE
• Start the Debugger-IDE and create a remote debug configuration. Make sure to connect to localhost on port 8211

• Start the debug configuration

@akoch-yatta I'm passing it to you since I'm working on the failed builds.

I was focusing on creating a reproducer (ideally even a test) but I couldn't do it. I will add the setup I used to the description of this Issue so you can easily test things manually.

[akoch-yatta]

For testing, you can directly add the dependency in the Platform SDK and debug directly out of the runtime
