Bluemix remote debugging session not starting

Question

I have followed the Bluemix/Eclipse instructions to setup the Liberty servers in eclipse. Able to do everything with the Bluemix/eclipse tools except for remote debugging.

Receiving the following exceptions/errors when I select the "Enable Debug Mode" on my application under the servers.

Tried a longer Debug timeout but that has not helped. Any pointers?

TIA

Answer 1

You need to ensure that you've done the following:

1. Enabled & configured the debug App Management utility as indicated here (1).
2. Ensure that dev mode for Eclipse Tools is enabled as indicated here (2).
3. Enable Remote Debug in Eclipse Tools as indicate here (3).

(2) https://www.ng.bluemix.net/docs/manageapps/app_management.html#devmode

(3) https://www.ng.bluemix.net/docs/manageapps/eclipsetools/eclipsetools.html#remotedebug

Answer 2

The issue was with the JDK in use .... replaced the ORACLE JDK 7 with ORACLE JRE 8 and that resolved the issue.

Answer 3

Do you happens to be using IBM JDK to launch the workbench? There is an existing problem that we are tracking on the debug support using that combination. If you happens to be using that, can you try using an Orcale JDK 8 to see if that resolves the problem?
