-Painless has a strict whitelist for methods and classes to ensure all
-painless scripts are secure. Most of these methods are exposed directly
-from the Java Runtime Environment (JRE) while others are part of
-Elasticsearch or Painless itself. Below is a list of all available
-classes grouped with their respected methods. Clicking on the method
-name takes you to the documentation for that specific method.  Methods
-defined in the JRE also have a `(java 9)` link which can be used to see
-the method's documentation in Java 9.
+Painless has a strict whitelist for methods and classes per context to
