For the most part I agree.  The JLS is even unusually clear for a 
specification.  I find it easy to read.

However, that's for the most part.  There are sections I still struggle 
to read correctly, even when I understand the answer already.  For 
example, plowing through the Final Field Semantics part of the JLS 
Memory Model, there's a part where the spec formally defines the 
Dereference Chain and the Memory Chain for final field semantics.  I 
think I understand what they are saying, because I know the answer from 
reading Java Concurrency in Practice, but I'm not sure I could correctly 
derive the answers in JCiP from the description they give.  (However the 
description before that part is pretty clear on the effects of final 
fields.)

Note that this really don't apply to enums, which I think are much more 
clearly written.  Although I admit I didn't try reading that part of the 
JLS again before replying here.

So overall, yes, folks should try to read the JLS, or learn how as Lew 
suggests.  But given that the JLS might not always be 100% clear, it's 
also OK to ask questions.  The overriding concern in this thread seems 
to be that Roedy didn't make an attempt to read or understand the JLS, 
he just expected CLJH to do his (home-) work for him.
