> At the time Java supported applets and webstart, a special mechanism for > launching various applications in one JVM was used to reduce memory usage and > each application was isolated from each other. > > This isolation was implemented via ThreadGroups where each application > created its own thread group and all data for the application was stored in > the context of its own group. > > Some parts of the JDK used ThreadGroups directly, others used special classes > like sun.awt.AppContext. > > Such sandboxing became useless since the plugin and webstart are no longer > supported and were removed in jdk11. > > Note that this is just a first step for the overall cleanup, here is my plan: > 1. Cleanup the usage of AppContext in the “java.util.logging.LogManager" > class in the java.base module. > 2. Cleanup the usage of TheadGroup in the JavaSound > 3. Cleanup the usage of TheadGroup in the JavaBeans > 4. Cleanup the usage of AppContext in the Swing > 5. Cleanup the usage of AppContext in the AWT > 6. Delete the AppContext class. > > The current PR is for the first step. So 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.
