Access java enumerators from an external jar file?

Hello,
I have an external jar file that I am using inside my Mathematica notebook.
This jar contains class and methods. One of the class contains some nested classes that I am loading by using
LoadJavaClass[“myclass$nestedclass”]

the nestedclass has not constructors but just some filds that are static string enumators.
Is there any way to access to those enumerators?
Thank you
Best regards
P

Out[2]= JLink`JavaClass["java.text.Normalizer$Form", 2, {
JLink`JVM["vm1"]}, 3, "java`text`Normalizer$Form`", False, True]
