Hi Chris,
Thank you for the review!
Yes, it is fixed now:
----------System.out:(27/1669)----------
vmOpts: ''
javaOpts: ''
JVM version:13-internal
JDI version: 13.0
JVM description: Java Debug Interface (Reference Implementation) version
13.0
Java Debug Wire Protocol (Reference Implementation) version 13.0
JVM Debug Interface version 13.0
JVM version 13-internal (Java HotSpot(TM) 64-Bit Server VM, mixed mode,
sharing)
Howdy!
Visible variables at this point are:
I think, it is Okay to print JVM version as it is now (13-internal).
Thanks,
Serguei
