Deploy Cluster Singleton blocks and never returns

[jeansafar <je...@matrics.io>]

Hi, 

I am deploying a few Cluster Singletons in my prototype. The first one is
deployed successfully yet the second one blocks and never return due to a
lock in GridFutureAdapter: 

    private R get0(boolean ignoreInterrupts) throws IgniteCheckedException {
        if (isDone() || !registerWaiter(Thread.currentThread()))
            return resolve();

        boolean interrupted = false;

        try {
            while (true) {
                LockSupport.park();  *<--- block point* 

Any pointer and help would be appreciated as I can't understand the pattern
here. 

Java 8 144 / service deployment done within spring boot Service
instantiation

best regards-
jean

Hi Jean!

What is your service configuration? Maybe you specified some node filter,
that doesn't accept any nodes?

There is also a known issue with services with injected Spring resources:
https://issues.apache.org/jira/browse/IGNITE-6555
Do you have something like that in your service implementation?
