--------------------------------------------
Summary: IllegalAccessException in Java 17
Key: FREEMARKER-216
URL: https://issues.apache.org/jira/browse/FREEMARKER-216
Project: Apache Freemarker
Issue Type: Bug
Components: engine
Affects Versions: 2.3.32
Reporter: Christopher Smith
I am using Freemarker in an annotation processor to generate code. I supply an
instance of {{javax.lang.model.element.TypeElement}}, which implements
{{QualifiedNameable}}, to the template model and use {{element.qualifiedName}}
as a template variable.
My code works fine under Java 11, but after updating the compiler to Java 17
(even with Java 11 compliance settings), I am receiving an
{{IllegalAccessException}}.
There seems to be a severely deficient implementation in the encapsulation of
Java internals that does not make methods that implement an interface
accessible, but perhaps it's possible to get the {{Method}} handles for the
property accessors on interfaces?
{code}
Caused by: java.lang.IllegalAccessException: class
freemarker.ext.beans.BeansWrapper cannot access class
com.sun.tools.javac.code.Symbol$ClassSymbol (in module jdk.compiler) because
module jdk.compiler does not export com.sun.tools.javac.code to unnamed module
