make test fails, gradle can't ID java version

I have Gradle 4.7 installed on OS X via `brew install gradle`.

Output of `java -version` is

```
java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)
```

Testing output is below. Strangely, it kept running after the java test failure for ~190 seconds (!) if I'm reading it correctly.

```
make test
go test -v -i ./testing
