Handle thread pool queue rejection when invoking rxjava code ------------------------------------------------------------ Key: ISPN-10943 URL: https://issues.jboss.org/browse/ISPN-10943 Project: Infinispan Issue Type: Bug Components: Core Reporter: Will Burns Assignee: Will Burns Priority: Major Fix For: 10.1.0.Beta1 Currently the BlockingRejectedExecutionHandler throws a Rejected exception at https://github.com/infinispan/infinispan/blob/master/commons/src/main/jav... when a non blocking thread can't pass a task to the blocking queue. Unfortunately in rxjava 2 they catch the exception and log it and do nothing else at https://github.com/ReactiveX/RxJava/blob/2.x/src/main/java/io/reactivex/i.... This leads to having a publisher that never completes. We should be able to throw a different exception, not RejectedExecutionException, and rxjava2 should catch and properly set it in the publisher to prevent this from happening.
