Hi, in case it wasn't reported before.
On Ignite.close we got an Error: ``` SEVERE: Failed to stop component (ignoring): GridManagerAdapter [enabled=true, name=o.a.i.i.managers.deployment.GridDeploymentManager] java.lang.ClassCastException: (java.io.ObjectInputStream$Caches$1 and java.util.Map are in module java.base of loader 'bootstrap') at org.apache.ignite.internal.managers.deployment.GridDeploymentStoreAdapter.clearSerializationCache(GridDeploymentStoreAdapter.java:151) at org.apache.ignite.internal.managers.deployment.GridDeploymentStoreAdapter.clearSerializationCaches(GridDeploymentStoreAdapter.java:120) at org.apache.ignite.internal.managers.deployment.GridDeploymentLocalStore.undeploy(GridDeploymentLocalStore.java:565) at org.apache.ignite.internal.managers.deployment.GridDeploymentLocalStore.stop(GridDeploymentLocalStore.java:101) at org.apache.ignite.internal.managers.deployment.GridDeploymentManager.storesStop(GridDeploymentManager.java:630) at org.apache.ignite.internal.managers.deployment.GridDeploymentManager.stop(GridDeploymentManager.java:137) at org.apache.ignite.internal.IgniteKernal.stop0(IgniteKernal.java:1928) at org.apache.ignite.internal.IgniteKernal.stop(IgniteKernal.java:1806) at org.apache.ignite.internal.IgnitionEx$IgniteNamedInstance.stop0(IgnitionEx.java:2382) at org.apache.ignite.internal.IgnitionEx$IgniteNamedInstance.stop(IgnitionEx.java:2205) at org.apache.ignite.internal.IgnitionEx.stop(IgnitionEx.java:350) at org.apache.ignite.Ignition.stop(Ignition.java:230) at org.apache.ignite.internal.IgniteKernal.close(IgniteKernal.java:2776) ``` ver. 2.13.0#20220420-sha1:551f6ece OS: Linux 4.15.0-189-generic amd64 VM information: OpenJDK Runtime Environment 11.0.16+8-post-Ubuntu-0ubuntu118.04 Ubuntu OpenJDK 64-Bit Server VM 11.0.16+8-post-Ubuntu-0ubuntu118.04 The reason for this Exception is an access to an field of ObjectOutputStream$Caches.subclassAudits which used to be of type java.util.Map but it changed to type java.lang.ClassValue! ``` org.apache.ignite.internal.managers.deployment.GridDeploymentStoreAdapter::clearSerializationCaches clearSerializationCache(Class.forName("java.io.ObjectInputStream$Caches"), "subclassAudits"); clearSerializationCache(Class.forName("java.io.ObjectOutputStream$Caches"), "subclassAudits"); clearSerializationCache(Class.forName("java.io.ObjectStreamClass$Caches"), "localDescs"); clearSerializationCache(Class.forName("java.io.ObjectStreamClass$Caches"), "reflectors"); ``` Is it safe to ignore this Exception? Any workarounds?
