Debug with DAP fails

[akurtakov]

Let's make sure issue is not already fixed in snapshots first.

• I verified I can reproduce this issue against latest snapshots build

Steps to reproduce

From a fresh installation and clean workspace:

• Ctrl+3
• Debug with VScode Java Debug Adapter

I expected: Debugging starts

But got: Error dialog with:

Error executing 'com.redhat.eclipseide.jdtlsclient.debugwithvscode': java.lang.NullPointerException: Cannot invoke "java.util.Map.putAll(java.util.Map)" because "builder.dspParameters" is null
Error executing 'com.redhat.eclipseide.jdtlsclient.debugwithvscode': java.lang.NullPointerException: Cannot invoke "java.util.Map.putAll(java.util.Map)" because "builder.dspParameters" is null

• I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.

Seems like eclipse-lsp4e/lsp4e#756 broke it . It removed DSPLaunchDelegate.jsonToMap which made sure that dspParameters is initialized while the new code doesn't do so.
