Test runner fails when no java opts are specified

[lread]

While helping out with editing poly docs, I decided to give the external test runner a whirl.

Working from the poly example tutorial project, if I configure the external test runner as described in the README and then run:

clojure -M:poly test

I get:

Projects to run tests from: command-line

Could not create valid test runner for the command-line project: java.lang.NullPointerException: Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null
Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null

The fact that poly is swallowing the stack trace doesn't help much, but I found if I provide some java opts:

POLY_TEST_JVM_OPTS=-Dfoo.bar=true clojure -M:poly test

All seems good:

Projects to run tests from: command-line

Running tests for the command-line project using test runner: Polylith org.corfield.external-test-runner...

Seems like the current code might be assuming java opts are always set?

Nice catch! I've never run it without at least some JVM options... oops!

Thanks @seancorfield, 0.3.0 fixes the issue for me!
