Karma becomes unresponsive instead of failing

I'm starting my Karma like this (in Java) :

```java
ArrayList<String> karmaTestCommand = new ArrayList<String>();
boolean isWindows = System.getProperty("os.name").startsWith("Windows");
if (isWindows) {
  karmaTestCommand.add("cmd"); //on Windows, NPM is not an executable, but a .cmd file
  karmaTestCommand.add("/c");
}
karmaTestCommand.add("npm");
karmaTestCommand.add("run");
karmaTestCommand.add("test");

ProcessBuilder karmaProcessBuilder = new ProcessBuilder(karmaTestCommand);
karmaProcessBuilder.inheritIO();
Map<String, String> karmaProcessEnv = karmaProcessBuilder.environment();
karmaProcessEnv.put("RIA_TESTSERVER_PORT", Integer.toString(testserverPort));
karmaProcessEnv.put("KARMA_SERVER_PORT", Integer.toString(karmaServerPort));
Process karmaProcess = karmaProcessBuilder.start();

boolean completed = new ProcessWatchDog(karmaProcess).waitFor(20, TimeUnit.MINUTES);
if (!completed) {
  System.err.println("Tests timed out after 20 minutes!");
  RIATestReport.writeTestTimeoutReport("target/junit_reports/test-results.xml", RunKarmaTests.class.getName());
}
```

This starts the following script :

```json
"scripts": {
  "test": "karma start common/test/karma/karma.conf.js --singleRun=true || (exit 0)"
}
```

Due to some issue with Firefox on one of our Jenkins slaves, Karma behaves like this :

```
[java] 02 04 2019 14:06:25.834:WARN [launcher]: Firefox have not captured in 60000 ms, killing.

```

This causes Karma to become unresponsive and will result in the process reaching a timeout after 20 minutes.

Is there any was I can get this process to end immediately, so I don't block my Jenkins slave for nothing?
