Class JavaSerializer.ObjectInputStreamWithKryoClassLoader

java.lang.Object

java.io.InputStream

com.esotericsoftware.kryo.serializers.JavaSerializer.ObjectInputStreamWithKryoClassLoader

All Implemented Interfaces:

Closeable, DataInput, ObjectInput, ObjectStreamConstants, AutoCloseable

Enclosing class:

JavaSerializer

private static class JavaSerializer.ObjectInputStreamWithKryoClassLoader
extends ObjectInputStream

$ObjectInputStream uses the last user-defined $ClassLoader which may not be the correct one. This is a known Java issue and is often solved by using a specific class loader.
