Spring Expression Language cannot resolve method on class

I'm trying to evaluate some expression written in SpEL programmatically.
ExpressionParser expressionParser = new SpelExpressionParser();
Expression expression = expressionParser.parseExpression(annotation.filter());
SimpleEvaluationContext context = SimpleEvaluationContext.forReadOnlyDataBinding().build();
context.setVariable("authorities", authentication.getAuthorities());
return expression.getValue(context, Boolean.class);
As you can see, I add a variable, called authorities. I'm trying to evaluate this expression: #authorities.isEmpty().
But I get the exception:
Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1004E: Method call: Method isEmpty() cannot be found on type java.util.ArrayList
at org.springframework.expression.spel.ast.MethodReference.findAccessorForMethod(MethodReference.java:225) ~[spring-expression-5.1.2.RELEASE.jar:5.1.2.RELEASE]
at org.springframework.expression.spel.ast.MethodReference.getValueInternal(MethodReference.java:134) ~[spring-expression-5.1.2.RELEASE.jar:5.1.2.RELEASE]
...
Anyone knows a solution to this problem?

The SimpleEvaluationContext does not allow arbitrary method invocation. See its Javadocs.
If you "trust" the SpEL expression, use
StandardEvaluationContext context = new StandardEvaluationContext();
