jdk 11下面出错

因为即使加了各种的 --add-exports，在 jdk.hotspot.agent 里，是在 sun.jvm.hotspot.tools.jcore.ClassDump.run() 里 ，用Class.forName 来加载filter类的。用户自定义的类加载不到。

    public void run() {
        // Ready to go with the database...
        try {
            if (classFilter == null) {
                // If not already set, the name of the filter comes from a System property.
                // If we have a pkgList, pass it, otherwise let the filter read
                // its own System property for the list of classes.
                String filterClassName = System.getProperty("sun.jvm.hotspot.tools.jcore.filter",
                                                            "sun.jvm.hotspot.tools.jcore.PackageNameFilter");
                try {
                    Class filterClass = Class.forName(filterClassName);
                    if (pkgList == null) {
                        classFilter = (ClassFilter) filterClass.newInstance();
                    } else {
                        Constructor con = filterClass.getConstructor(String.class);
                        classFilter = (ClassFilter) con.newInstance(pkgList);
                    }
                } catch(Exception exp) {
                    System.err.println("Warning: Can not create class filter!");
                }
            }
