--------------------------------------
Summary: NetBeans fails silently if it can't attach a debugger
Key: NETBEANS-3226
URL: https://issues.apache.org/jira/browse/NETBEANS-3226
Project: NetBeans
Issue Type: Bug
Components: debugger - Java
Affects Versions: 11.1, 11.2
Reporter: Scott Palmer
When trying to attach a debugger to an existing Java process, the operation
simply does nothing if the attempt fails with no feedback to the user.
messages.log contains details, but note the odd repetition of the attach
parameters in the log messages:
