Hi all,
Please review a change for JDK-8188858.
Bug report: https://bugs.openjdk.java.net/browse/JDK-8188858
Webrev: http://cr.openjdk.java.net/~horii/8188858/webrev.00/
This change caches the result of latestUserDefinedLoader() when objects
are deserialized, so the decerializer can avoid redundant stack walking to
resolve classes of deserializing objects.
Some of the bugs/abuses of OIS come about from calling it on different
threads with different contexts. So I think this optimization can only
work if to confine it to the thread calling readUnshared, meaning
readResolve cannot skip latestUserDefinedLoader() when called on other
threads.
