I think this must fix before M9

Why do you think that it should be fixed for M9? I doubt that binding in module 
project is a blocker for anything. Note that the binding library is even not 
present in the IDE as a NB library that can be added on the classpath of module 
projects.

Moreover, so far, you are the only one who is able to reproduce this issue. Are 
you able to reproduce this issue with a clean userdir and some official build 
(downloaded for example from bits.netbeans.org)?

After clean userdir It works

go here and see how to reproduce it    <a

The use-case described in issue 103614 is really strange. I don't see a reason 
for copying j2ee jars into platform cluster. It seems that it puts different 
version of javax.el classes of the classpath used by form module. IMHO you 
shouldn't do things like this.
