Matlab problem using java enumerators

Hello, I have a problem using java enumerator in Matlab. I tried to use some suggestion available in some references like the Altman book but not in all the situation I have the solution proposed work fine. For example here below there is a case where enumerator created in java I am not able to capture

I have an external jar with the following class

com.myClass.enumMethods

If I see the methods from Matlab, they appear in this way myClass$enumMethods.

In Java, this enumerators have the following properties:

Enclosing class: myClass

public static final class myClass.enumMethods extends Object

Enumeration type for myClass. The following values are allowed: * ENUM_1 * ENUM_2 * ENUM_3

Field Summary: static myClass.EnumMethods ENUM_1 static myClass.EnumMethods ENUM_2 static myClass.EnumMethods ENUM_3

Thank you in advance for the help
