Hi,
I am looking at internal API usage that we (likely) have to remove during
the JDK 11 upgrade effort.
The jdeps tool can scan jars and find internal API usage, so I used it.
I've already run it on jai-ext (no complaints)
and imageio-ext (see results at
https://github.com/geosolutions-it/imageio-ext/issues/172 ).
Here are the results running it onto GeoTools (I've collected the GeoTools
jars, release style, went into target/binaries, and run jdeps):

Warning: JDK internal APIs are unsupported and private to JDK
implementation that are
subject to be removed or changed incompatibly and could break your
application.
Please modify your code to eliminate dependence on any JDK internal APIs.

JDK Internal API Suggested Replacement
---------------- ---------------------
com.sun.image.codec.jpeg.ImageFormatException Use javax.imageio @since 1.4
com.sun.image.codec.jpeg.JPEGCodec Use javax.imageio @since 1.4
com.sun.image.codec.jpeg.JPEGDecodeParam Use javax.imageio @since 1.4
com.sun.image.codec.jpeg.JPEGEncodeParam Use javax.imageio @since 1.4
com.sun.image.codec.jpeg.JPEGImageDecoder Use javax.imageio @since 1.4
com.sun.image.codec.jpeg.JPEGImageEncoder Use javax.imageio @since 1.4
com.sun.image.codec.jpeg.JPEGQTable Use javax.imageio @since 1.4
java.awt.peer.ComponentPeer Should not use. See
https://bugs.openjdk.java.net/browse/JDK-8037739
sun.awt.image.codec.JPEGParam Use javax.imageio @since 1.4
sun.misc.Unsafe See
http://openjdk.java.net/jeps/260
sun.security.action.GetPropertyAction Use java.security.PrivilegedAction
@since 1.1
As you can see part of the report is due to imageoi-ext jars in the
collection (I've made it light gray), but the rest seems legit and
points to both GeoTools sources and some dependencies.
Cheers
Andrea
