> With CDS and G1, test api/java_lang/ModuleLayer/Boot.html fails in JDK 16. > > After JDK-8253081 with CDS enabled two instances of empty layer appear in the > runtime. One comes from default initialization of > java/lang/ModuleLayer.EMPTY_LAYER, another one comes from CDS archive and is > returned by ModuleLayer.boot().parents().get(0). The fix makes > java/lang/ModuleLayer.EMPTY_LAYER a singleton with both CDS on and off, > similar to java/lang/module/Configuration.EMPTY_CONFIGURATION. > > Testing: JCK 16, jtreg (including newly added test), pre-submit GitHub > actions tests.
