Looks okay.

Nit:  the type name returned in javadoc and @param should be wrapped 
with {@code ...}.

These lines are some example:
2235      * @param  s the ObjectOutputStream to which data is written

  941      * The BytecodeGenerationException.

261 * Resolve a SerializedLambda to an object. No need for a new webrev.
