Description
Fix for JDK-8057588 was incomplete. Running the fresh Nashorn with dumping all classes: ~/trunks/jdk9-dev/build/linux-x86_64-normal-server-release/images/j2sdk-image/bin/java -jar ~/trunks/jdk9-dev/build/linux-x86_64-normal-server-release/images/j2sdk-image/jre/lib/ext/nashorn.jar -Dnashorn.typeInfo.disabled=false --class-cache-size=0 --persistent-code-cache=false -scripting --log=time -d=generated/ test/script/basic/compile-octane.js -- --iterations 1 ...still yields lots of trivial classes. 2300/3900 of all classes are those trivial. http://cr.openjdk.java.net/~shade/8057703/nashorn-generated-classes-2.list Also, the additional stage introduced in JDK-8057588 takes considerable time: [time] 'Tag Compile Units Used' 1231 ms
