[infinispan-issues] [JBoss JIRA] (ISPN-10073) Nested async operations with HotRod client hang

[ https://issues.jboss.org/browse/ISPN-10073?page=com.atlassian.jira.plugin... ] Dejan Bosanac updated ISPN-10073: --------------------------------- Description: We noticed some issued with the HotRod client, when trying to use nested async calls. Originally, this was discovered in the context of Vert.x tests, but below you can find the smallest reproducer code that I could create (without any Vert.x dependencies). {code:java} //DefaultCacheManager cm = new DefaultCacheManager(); //Cache<String, String> cache = cm.createCache("default", new ConfigurationBuilder().build()); RemoteCacheManager cm = new RemoteCacheManager(); RemoteCache<String, String> cache = manager.getCache("default"); final CompletableFuture put = new CompletableFuture(); cache.putIfAbsentAsync("A", "A").thenAccept(resultA -> { final CompletableFuture nested = new CompletableFuture(); cache.putIfAbsentAsync("B", "B").thenAccept(resultB -> { nested.complete("B"); }); try { nested.get(); } catch (Exception e) { e.printStackTrace(); } put.complete("B"); }); put.get(); {code} Everything works as expected with embedded cache. was: We noticed some issued with the HotRod client, when trying to use nested async calls.
