Description

I am trying to get a class object for a JCas FS type using reflection:

Class.forName(typeName);

However, it produces this strange error.

java.lang.ExceptionInInitializerError
	at java.lang.Class.forName0(Native Method)
	at java.lang.Class.forName(Class.java:264)
...
Caused by: org.apache.uima.cas.CASRuntimeException: A JCas class field "sofa" is being initialized by non-framework (user) code before Type System Commit for a type system with a corresponding type. Either change the user load code to not do initialize, or to defer it until after the type system commit.

	at org.apache.uima.jcas.cas.AnnotationBase.<clinit>(AnnotationBase.java:71)

Is it considered harmful to try getting a class object for a JCas FS class?
