public final class ReflectPermission
The Permission class for reflective operations. A ReflectPermission is a named permission and has no actions. The only name currently defined is suppressAccessChecks, which allows suppressing the standard Java language access checks -- for public, default (package) access, protected, and private members -- performed by reflected objects at their point of use.
The following table provides a summary description of what the permission allows, and discusses the risks of granting code the permission.
| Permission Target Name | What the Permission Allows | Risks of Allowing this Permission |
|---|---|---|
| suppressAccessChecks | ability to access fields and invoke methods in a class. Note that this includes not only public, but protected and private fields and methods as well. | This is dangerous in that information (possibly confidential) and methods normally unavailable would be accessible to malicious code. |
