JDK 11 compiler speed doesn't scale well with the number of jar files on Windows.

The performance of com.sun.tools.javac.Main#compile() is slower in JDK 11 than JDK 8. The difference is getting larger as the loaded jar files are increased. The similar performance degradation is not observed in other platforms.
