-Add --add-opens for necessary modules/packages
-- java.base/java.lang - for reflection access to Proxy.proxyCache
-- java.base/jdk.internal.loader - for access proxyCache class
-- java.desktop/java.beans - for reflection access to Introspector
-
-- be quiet if HotswapAgent is not found in lib/, it is compatible with
-old DCEVM
-- disable hotswapagent for -Xshare:dump
-- disable HotswapAgent in jvm tools
