Character "-" in the name attribute of the <binding> element

When declaring a bindg with the "-" caracter in the name attribute of the <binding> element this exeption is throwed when executing the .class method to the binded class.
Example:
<binding name="some-name">
<mapping name="filter-group" class="MyClass">
<value name="logical-operator" field="attA"/>
<collection field="attB"/>
</mapping>
</binding>
public MyClass {
private String attA;
private ArrayList<String> attB;
}
The JiBX binder runs fine, but when executing MyClass.class this error is throwed
java.lang.LinkageError: LinkageError while defining class: MyClass
Could not be defined due to: (MyClass) method name is invalid at offset=0
This is often caused by having a class defined at multiple
locations within the classloader hierarchy. Other potential causes
include compiling against an older or newer version of the class
that has an incompatible method signature.
