Re: [glassfish-dev] GlassFish updates for the javax -> jakarta transitio

[Bill Shannon <bill.shannon@xxxxxxxxxx>]

    Ok, I think I'm starting to catch up...
    
    There's 5 usages of pfl-asm stuff in GlassFish.  If we fix those 5
    usages to use the new API, then they can use the new version of
    pfl-asm that works with JDK 11.
    
    Is that right?
    
    You mention eliminating them below but I'm not sure what that
    involves.  That would mean taking these 5 usages and converting them
    to not use pfl-asm and use something else instead?  That sounds like
    a much bigger job than converting them to use a new pfl-asm API.  Do
    you think this is worth pursuing?

The ORB does not depend on Glassfish, so it would be difficult automatically to use the same version, I suspect. But if the pfl-asm dependency is removed from Glassfish, I can work on getting rid of it completely. I believe that other parts of gmbal-pfl still need it.

Sorry, I'm not following what it is you think needs to be done here.

I have no idea whether GlassFish is using pfl-asm directly, although certainly
it is using it indirectly because it's using the ORB and the ORB is using it,
right?

A search of the build.xml files in Glassfish shows 5 usages each of pfl-asm, pfl-tf-tools and pfl-basic-tools. I think we would like to eliminate them, if possible. 

Currently, the ORB is built so that it should run under JDK11 (pfl-basic is an MR jar). Some additional work will be needed in Glassfish to take advantage of that.

What kind of work would be needed in GlassFish?

How is pfl-basic related to orb-gmbal-pfl?

orb-gmbal-pfl used to be called, simply, pfl, and consists of a number of projects, including some only used for testing. I’d like to get rid of the latter. The important ones are pfl-basic and pfl-dynamic.

And those are in an MR jar that works in JDK 11?

So there's no need to get rid of pfl-basic or pfl-dynamic, right?

Correct.

In fact, I don't think this will need to be done, but we will need the entire
ORB and RMI-IIOP support to work correctly in a JDK 11 runtime, as part of
providing backward compatibility for those products that need it (e.g.,
WebLogic), including EJB interoperability support.

I’ve already done that work for WebLogic. Glassfish just needs to use the updated APIs, I believe.

Is that work already in the Eclipse project?

Yes.

What's involved in converting GlassFish to use the updated APIs?

I’ll have to do some research on that point.
