> I am trying to get a class object for a JCas FS type using reflection:
> {noformat}
> Class.forName(typeName);
> {noformat}
> However, it produces this strange error.
> {noformat}
> 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.

> {noformat}
> Is it considered harmful to try getting a class object for a JCas FS class?
