static final int PROTOCOL_VERSION_1
All externalizable data is written in JDK 1.1 external data format after calling this method. This version is needed to write streams containing Externalizable data that can be read by pre-JDK 1.1.6 JVMs.
static final int PROTOCOL_VERSION_2
This protocol is written by JVM 1.2. Externalizable data is written in block data mode and is terminated with TC_ENDBLOCKDATA. Externalizable classdescriptor flags has SC_BLOCK_DATA enabled. JVM 1.1.6 and greater can read this format change. Enables writing a nonSerializable class descriptor into the stream. The serialVersionUID of a nonSerializable class is set to 0L.
