NPE in JobConsumerExecutor

[andhie]

In JobConsumerExecutor.java the method below causes a NPE due to val being null

private boolean contains(String[] arr, String val) {
    for (int i = 0; i < arr.length; i ++) {
        if (val.equals(arr[i])) {
            return true;
        }
    }
    return false;
}

I'm implementing ActivityBoundJobs as described in the Wiki, and cancelling Jobs when activity goes onStop().
Scenario: Activity1 launches Activity2. Activity2 calls an API to get data and JobConsumerExecutor crashes

@Override
protected void onStop() {
    super.onStop();
    MyApplication.getInstance()
            .getJobManager()
            .cancelJobsInBackground(null, TagConstraint.ANY, sessionId);
}

are you sure you are not passing null sessionId?
