In older and newer 2.3.x Versions this seems not to work either.

It is used on bean validation. No error or warning occurs, it silently just doesn't validate.

Actually, shouldn't the private javax.faces.validator.ValueExpressionAnalyzer be replaced by using ValueExpression#getValueReference?

Although this is currently blocked because ValueReference can't be obtained from a TagValueExpression in JSF 2.x (since it doesn't implement getValueReference and its super class just returns null).

In fact, javax.faces.validator.BeanValidator already mentions this in comments:

// PENDING(rlubke, driscoll): When EL 1.3 is present, we won't need
// this.

ValueExpressionAnalyzer expressionAnalyzer =
new ValueExpressionAnalyzer(valueExpression);
