MyFaces encompasses 11 subprojects, so it's going to take a lot of
resources to check all of them.
I know that there was a dependency fixed for the MyFaces Tomahawk
examples to the sun image package in the last couple of months.

I quickly checked but had not enough spare time to dig deeper.
Probably doing in the next days.
Txs for the ping though, higly appreciated!

Hi,
Just wondering if anyone has had a chance to run the jdeps tool to check for
dependencies on JDK-Internal APIs ?

Hi,
My name is Rory O'Donnell, I am the OpenJDK Quality Group Lead.
I'm contacting you because your open source project seems to be a very popular
dependency for other open source projects.
As part of the preparations for JDK 9, Oracle’s engineers have been analyzing
open source projects like yours to understand usage. One area of concern
involves identifying compatibility problems, such as reliance on JDK-internal
APIs.
Our engineers have already prepared guidance on migrating some of the more
common usage patterns of JDK-internal APIs to supported public interfaces. The
list is on the OpenJDK wiki [0].
As part of the ongoing development of JDK 9, I would like to inquire about your
usage of JDK-internal APIs and to encourage migration towards supported Java
APIs if necessary.
The first step is to identify if your application(s) is leveraging internal
APIs.
Step 1: Download JDeps.
Just download a preview release of JDK8(JDeps Download). You do not need to
actually test or run your application on JDK8. JDeps(Docs) looks through JAR
files and identifies which JAR files use internal APIs and then lists those
APIs.
Step 2: To run JDeps against an application. The command looks like:
jdk8/bin/jdeps -P -jdkinternals *.jar > your-application.jdeps.txt
The output inside your-application.jdeps.txt will look like:
your.package (Filename.jar)
-> com.sun.corba.se JDK internal API (rt.jar)
3rd party library using Internal APIs:
If your analysis uncovers a third-party component that you rely on, you can
contact the provider and let them know of the upcoming changes. You can then
either work with the provider to get an updated library that won't rely on
Internal APIs, or you can find an alternative provider for the capabilities
that the offending library provides.
Dynamic use of Internal APIs:
JDeps can not detect dynamic use of internal APIs, for example through
reflection, service loaders and similar mechanisms.
