I get the same problem as Bluemix remote debugging session not starting when trying to debug my web app on Bluemix Tomcat server from Eclipse, following the steps below.
- Fresh installed eclipse-jee-neon-R-win32-x86_64 and all required Eclipse plugins (e.g., the Eclipse tools for Bluemix for Neon,).
- Created a new Cloud Foundry App in Bluemix, selected Tomcat as runtime, then Add Git and build and deploy the sample web app which called 'TomcatHelloWorldApp'.
- Clone the 'TomcatHelloWorldApp' web app to my Eclipse from Jazz Git repository.
- Created new IBM Bluemix server in Eclipse, add and push the 'TomcatHelloWorldApp' web app.
- Right check the web app under the IBM Bluemix server and select 'Enable Application Debug'.
But, I get the error below. It doesn't work even with the default web app created by Bluemix:

Then I try to modify the code and make it work fine with Java 1.8 Modify the Maven pom.xml file as
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
Add below settings in the manifest.yml file.
env:
JBP_CONFIG_IBMJDK: '[version: 1.8.+]'
JBP_CONFIG_LIBERTY: 'app_archive: {features: [websocket-1.1, servlet-3.1]}
Also modify the Build Shell Command as below
#!/bin/bash
export JAVA_HOME=/opt/IBM/java8
mvn -B package
It builds and deploys successfully, and works fine with Java 1.8 now.
But when I try to 'Enable Application Debug', I got the same problem again... Can you please give any help on this?
