RFR: 7194 : No local JVMs found message could be more helpful

[Michael S.]

The message refers to the FAQ to question 
"Q: I cannot see any locally running JVMs in the JVM browser!" 
Suggestion for new answer
A3: Are you running a JDK <11? You must specify a JDK >=11 either via PATH of by adding "-vm" parameter in jmc.ini (before -vmargs parameter; value is path to JDK bin folder)
