If you are using a class filter, then Nashorn prevents access to. If you are using a security manager, then Nashorn allows a script to use the Java Reflection APIs (for example, the and packages) only if the script has the nashorn.javaReflection run time permission. To summarize this somewhat complex situation, see Table 1, which shows the version changes in the permitted access to JDK internals. Restricting Access to Java Reflection APIs. This topic is covered in detail by JEP 403: Strongly encapsulate JDK internals. Nevertheless, to become an advanced Java developer, gaining a solid understanding of reflection (also. However, it is frequently misunderstood or misused, and certain aspects of its API and design are rather clunky and, in places, out of date. The Java security manager uses the Java security policy file to enforce a set of permissions granted to classes.

However, in Java 17, the situation changes again: This release removes that command-line switch. Reflection is one of the most flexible and powerful techniques Java developers have at their command. The JVM has security mechanisms built into it that allow you to define restrictions to code through a Java security policy file.
