-// Usage: jjs disassemble.js -- <.class-file-path>
-
-// Simple .class disassembler that uses bundled ObjectWeb ASM
-// classes in jdk8. WARNING: Bundled ObjectWeb ASM classes are
-// not part of official jdk8 API. It can be changed/removed
-// without notice. So, this script is brittle by design!
-
-// This example demonstrates passing arguments to script
-// from jjs command line, nio and ASM usage.
-
-// classes used
-var FileSystems = Java.type("java.nio.file.FileSystems");
-var Files = Java.type("java.nio.file.Files");
-var System = Java.type("java.lang.System");
-var PrintWriter = Java.type("java.io.PrintWriter");

-// WARNING: uses non-API classes of jdk8!
-var ClassReader = Java.type("jdk.internal.org.objectweb.asm.ClassReader");
-var TraceClassVisitor = Java.type("jdk.internal.org.objectweb.asm.util.TraceClassVisitor");
