This patch replaces java.lang.invoke and JFR use of jdk.internal.misc.Unsafe::defineClass with Lookup::defineClass. It also replaces dynamic proxy and reflection implementation to use the shared secret to invoke ClassLoader::defineClass.
Webrev: http://cr.openjdk.java.net/~mchung/jdk12/webrevs/8181443/webrev.00 With this change, JDK no longer uses Unsafe::defineClass. Any opinion in removing Unsafe::defineClass support? I ran jdk_core, jdk_jfr, tier1_runtime and tier1_compiler tests. thanks Mandy
