Re: [jakartaee-platform-dev] Standardizing new TCK packages (was:package prefixes for Jakarta Batch TCK-related classes?org.eclipse.ee4j.batch ?)

At least org.glassfish still seems to be used.

I would like to point out that we do not use "org" anywhere with Jakarta at the moment. We do not own the jakarta.org domain name, for example. We do own and use the jakarta.ee domain name.

From my perspective, starting to use the .org TLD with Jakarta for this purpose might be confusing.

+1  for org.jakartatck.*     
(though OK with the other options)

Thanks David for making that an option and thanks all for giving this some thought.     Even though not too many people look at a TCK relatively speaking it seemed better to be good Java citizens and use a package of a domain name we own.

Thank you David for the detailed explanation! I now understood the concern.
The following package name might work:

-- tck.jakarta.<spec>.

In all, we could choose one from the list

org.jakartatck.*
ee.jakarta.tck.*
tck.jakarta.*

Thanks
Emily

I think I finally see what Romain is talking about.

I know in TomEE we have several optimizations to try and speed up deployment and bytecode scanning.  We'll filter out jars that match patterns like log4j-*, openejb-*, jakarta-*.  Those jars are removed from the list of jars that could potentially contain applications and they'll never be searched for annotations like @Singleton, etc.  Additionally, as everyone uses somewhat expensive bytecode readers like ASM to parse bytecode and scan for annotations, we have additional filters to skip non-application classes, such as javax.* and jakarta.*.  There are classloader related actions as well.

Here's an example we hit in EclipseLink when we tried to use the Eclipse Transformer to do the javax-to-jakarta change.

 -
https://github.com/eclipse-ee4j/eclipselink/blame/master/jpa/org.eclipse.persistence.jpa/src/main/java/org/eclipse/persistence/internal/jpa/deployment/JavaSECMPInitializer.java#L345

We were transforming EclipseLink 2.x which did not have the `!name.startsWith("jakarta.")` string check, so jakarta.* classes were getting loaded as application classes and causing most tests to fail.  We hit this in a few different libraries and ended up having to patch source to ensure "jakarta." and "Ljakarta/" were factored into any code that checked for "javax." as a package or "Ljavax/" as bytecode.

If we started putting the TCK tests in "jakarta.tck" and that also included the test applications we need to deploy and verify, that definitely will cause issues in a handful of component implementations we all use.

The only way to handle it would be to update code like this to have an exclusion that explicitly checks for "jakarta.tck" and ensures it is treated as user-created application code and bypasses any "javax" or "jakarta" checks.  That's going to mean there'll be code in our implementations that says essentially  "if your code starts with jakarta.tck, make sure it's treated correctly, otherwise do something else."  That could be a slippery slope.

It's probably better if we don't put ourselves in a situation were we have to write code to specially handle TCK applications.

It occurs to be in writing this that literally any characters before "jakarta" solves this issue.  If we want a short name, we do own the
jakarta.ee domain and can potentially use either of these:

 - ee.jakarta.*
 - ee.jakarta.tck.*

I also just looked and
jakartatck.org was available, so I purchased that and we could potentially use:

 - org.jakartatck.*

If we wanted to go that direction, I'd just transfer
jakartatck.org to the Working Group like I did when purchased jakarta.ee.

We need to discuss this further to see whether it is correct to say so if it does have this sentence.

The risk is users start importing tck instead of the spec and application will work cause the spec comes transitively but it is not what jakarta wants, right? Making it clean is trivial and consistent with everything so I think it is worth not trying to be more clever than we need to.

It is much nicer to start with jakarta.tck to denote the TCK classes and also easily to filter out with pattern matching when searching for api classes. Besides it is much shorter than org.eclipse.jakarta.

It also has the advantage to not use jakarta.* package which is treated specifically by all implementations (by spec actually ;)) and would need some specific rules in the impl is used for tcks too which is not the target of the spec at all. Lastly it makes it obvious it is not part of the API for users so it is very good too. For me, it looks like a consistent and good compromise for everyone (foundation, users, vendors and spec contributors/legal).
