public class ShadowingPersistentInputStream extends io.deephaven.shadow.enterprise.com.fishlib.dataobjects.persistence.PersistentInputStream
Enterprise makes extensive use of Java serialization through WObjectOutput/InputStream. Those Stream implementations use a custom encoding to write the data too. The unfortunate consequence of this is that we'll end up with encoded package names that do not match our shadowed versions. This class attempts to dynamically rewrite certain package prefixes at load time into their shadowed versions.

    protected io.deephaven.shadow.enterprise.com.fishlib.dataobjects.persistence.WObjectInputStream.ObjectConverter
    getReaderForType(@NotNull String typeString)
    There are a few different paths within WObjectInputStream that resolve packages to real classes, this one handles the path when the object is plainly encoded in the stream.
