Here are a few thoughts on how you can determine the solution, it mainly comes down to how does the calling line of code know which instance its dealing with? Some possible answers are:
1. Are you creating a new instance? 2. Have you been handed an instance from somewhere else? 3. Are you accessing an existing instance from a variable?4. Is the method you are calling fom really meant to be static (normally only relevant when dealing with a method on the same class)?
Just going by the name startStyle, I suspect its option one, you need to create a new instance within the startStyle method, however don't take my word here as I am only going by the name of the method and not actually knowing what the method does.

Good question. In the startStyle method in the Styles class I was getting a compile error of "reference to nonstatic variable from static contgext." So I made semanticsTable static and introduced the getSemanticEntry method. semanticsTable really should not be static, as you say. How can I get around this?

I would have thought it was a prime example of an instance variable, the table is only relevant for that instance, which according to an earlier comment is for a given document. Why should the table of semantic actions be common to all instances, and so if I understand the earlier comment will be shared for all documents? Michael Whapples
