[jira] [Created] (IGNITE-10228) Start multiple caches in parallel
may lead to the fact that some of the caches won't be registered.

--------------------------------------------
Summary: Start multiple caches in parallel may lead to the fact that some of the caches won't be registered.
Key: IGNITE-10228
URL: https://issues.apache.org/jira/browse/IGNITE-10228
Project: Ignite
Issue Type: Bug
Components: cache
Affects Versions: 2.6
Reporter: Vyacheslav Koptilin
It looks like the root cause of the issue is that {{CacheGroupContext.addCacheContext()}} (which is called in parallel) does not use a lock/semaphore in order to synchronize {{caches}} updates.
{code:java}
private void addCacheContext(GridCacheContext cctx) {
ArrayList<GridCacheContext> caches = new ArrayList<>(this.caches);
boolean add = caches.add(cctx);
...
this.caches = caches;
}
{code}
