Hello, Please review java.desktop part of the changes for jdk9 that remove the support for serialized applets. Support for serialized applets was added in JDK 1.1 to allow an applet to be shipped in a pre-initialized state. Today, with modern compression and JVM performance there is no benefit to continuing to support this technology.
Jira issue: https://bugs.openjdk.java.net/browse/JDK-8134808 Webrev: http://cr.openjdk.java.net/~dtitov/8134808/webrev.00/ Thanks! Best regards, Daniil
