8260540: serviceability/jdwp/AllModulesCommandTest.java failed with "Debuggee error: 'ERROR: transport error 202: bind failed: Address already in use'"

[alexmenkov]

Updated AllModulesCommandTest to use dynamic port launching debuggee.
Parsing debuggee listening address functionality is required in several tests (and we have other tests which need to be fixed the same way), so moved the code to new class in jdk.test.lib

Ping

[sspitsyn]

What is going to happen in the case of addr == null?

[alexmenkov]

addr == null means we didn't get "listening for transport" output yet.
We continue to run the loop waiting for the parse-able output

[sspitsyn]

It looks good to me. Just one minor question inlined.
Thanks,
Serguei

OK, so we let the debugee JVM find its own port, and start using it, then JDWP.parseListenAddress() decodes the debugee output to find the port in use. findFreePort used previously was not working well, or was racing with other tests and clashing. Sounds good.

I'm not sure in Debugee.java why we use an array for: JDWP.ListenAddress[] listenAddress

We set the value of the local variable in lambda, so the variable must be final or (as in this case) effectively final
