Hi,
in case it wasn't reported before.
On Ignite.close we got an Error:
```

OS: Linux 4.15.0-189-generic amd64

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?
Thank you,
Best,
Rafael
