Why fullyQualifiedName method returning Recovered#typeBindingLMyVo;0

I want to get the full path(xxx.xxx.ClassName) of method’s parameter in my plugin with code MethodTree.parameters().get(X).type().symbolType().fullyQualifiedName().but if the parameter class is supplied by JDK it returns full path of parameter class ,if parameter is supplied by myself it returns “Recovered#typeBindingLMyVo;0”.

sonarQube version 8.9.3
java version 11.0.12

I need help.thanks.

It works well when I change the config named sonar.java.binaries to target/classes/
