RFR: 8273101: Eliminate the usage of threadgroup sandboxing in the java.util.logging

Thu Sep 2 08:20:53 UTC 2021

The "java.util.logging.LogManager" class uses the "threadgroup sandboxing" via an AppContext to support "applet logging isolation". The AppContext class became useless since the plugin and webstart are no longer supported and removed in jdk11.

This is the request to delete the usage of AppContext in the LogManager and related tests.

Tested by tier1/tier2/tier3 and jdk_desktop tests.
