    Description

      When a source file has a component annotation with an invalid value, e.g. @DefaultFactoryFor(classes = {NonExistentClass.class}), ComponentAnnotationProcessor hits a ClassCastException:

      Error:java: ComponentAnnotationProcessor unexpected error: java.lang.ClassCastException: class com.sun.tools.javac.code.Attribute$UnresolvedClass cannot be cast to class com.sun.tools.javac.code.Attribute$Class (com.sun.tools.javac.code.Attribute$UnresolvedClass and com.sun.tools.javac.code.Attribute$Class are in module jdk.compiler of loader 'app')

      IntelliJ shows the annotation processor error first, hiding the compilation error, while Maven only says

      [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project infinispan-core: Fatal error compiling: CompilerException: NullPointerException
