Running Gauge sample on command line runs forever without error

The report names the Java runner startup and package scanning as the last logged steps; start by reading the gauge-java runner logs and the code that scans packages for steps. Reproduce with the reported Java sample using gauge run specs/ and inspect where execution stops. Done means the sample completes and reports its scenarios, or the runner reports a clear error instead of hanging.

Describe the bug
I freshly installed gauge on command line via apt-get. I installed Gauge Java using "gauge install java". I created a sample project in /tmp/gaugesample

To Reproduce
Steps (or project) to reproduce the behavior:
/tmp$ mkdir gaugesample
/tmp$ cd gaugesample/
/tmp/gaugesample$ gauge init java
Initializing template from https://github.com/getgauge/template-java/releases/latest/download/java.zip
.
Copying Gauge template java to current directory ...
Successfully initialized the project. Run specifications with "gauge run specs/".
/tmp/gaugesample$ gauge run specs/
