Unable to run tests using openjdk16

The first init test fails.. with a parboiled InitializerError exception

[INFO] Running convex.core.init.InitTest
[ERROR] Tests run: 3, Failures: 0, Errors: 3, Skipped: 0, Time elapsed: 0.023 s <<< FAILURE! - in convex.core.init.InitTest

nearly all subsequent tests also fail..

Even if I get to compile and package the java. when I run it I get

Jul 05, 2021 5:06:55 PM convex.cli.LocalStart run
INFO: Starting local network with 8 peer(s)
Jul 05, 2021 5:06:55 PM convex.cli.Main execute
SEVERE: null

so looks like parboild rewrite is a go

Possibly related issues other people have run into:

• Fails to build with Java 16 immutables/immutables#1283
• address JDK 16 failures scala/community-build#1354

I believe this is fixed with the replacement of Parboiled with ANTLR
