> Creation of BDB VHN/VH via UI hangs without any error reported via REST or into broker logs when JE library is not available in the classpath. Additionally, Broker hangs to start-up when BDB VHN/VH are present in the configuration store but JE library is not available.
> The issues is caused by call to ListenableFuture.get() in AbstractConfiguredObject#doSync(ListenableFuture) . Errors like NoClassDefFoundError do not interrupt ListenableFuture.get() and swallowed in the ExecutorService. As result, configuration thread is waiting forever until Broker process is stopped.
