> {{LocalStreamManagerImpl}} checks in several places that the cache status is {{RUNNING}}, and if not it suspects all local segments with this log message:
> {noformat}
> [LocalStreamManagerImpl] Cache status is no longer running, all segments are now suspect for Test-NodeD-257370
> {noformat}
> This check is incorrect, because a node may receive distributed streaming requests before it is running: the initial state transfer could finish before all the components in the cache finish starting.
> If the check fails because the cache is still starting, the originator of the distributed stream iteration will assume that the remote cache has a newer topology. Because there is no newer topology, the originator blocks for {{DistributedCacheTimeout.timeout()}} and then fails.

> Immediately suspected that plain HashMap is being modified from multiple threads without proper synchronization. But since I'm new to Infinispan, I can't know whether the usage of plain HashMap in NonTxInvocationContext is intentional and Infinispan code is relying on some external synchronization to be performed by other parts of system that calls NonTxInvocationContext.[lookupEntry|removeLookedUpEntry|putLookedUpEntry|getLookedUpEntries]. In any way, if this external synchronization is taking place, it has a bug and allows calling these methods concurrently without proper synchronization.
> I did some experiments to prove that and also to obtain stack traces of at least two of involved threads, but trivial things that I tried instrumenting those methods all involved some kind of synchronization and the symptom disappeared. I had to be extra smart to obtain the stack traces of two threads without inter-thread synchronization so that I could detect the data race. Here's how I instrumented NonTxInvocationContext code:

> {{GlobalConfiguration}} uses a {{WeakReference}} to store its classloader, in order to allow {{JCachingProvider}} to use a {{WeakHashMap<ClassLoader, DefaultCacheManager>}}.
> The weak reference works fine when the classloader is the application classloader, but if the application (or the server, in our case) creates a {{ClassLoader}} instance just for the Infinispan configuration, that classloader can be garbage collected while the cache manager is starting. That is exactly what happens during server startup sometimes, making {{GlobalComponentRegistry}} use the TCCL for module initialization and ignoring all the non-core modules.
> We can still use a {{WeakClassLoader}} adapter that wraps a {{WeakReference<ClassLoader>}} for {{JCachingProvider}}.
