Build change looks good now.
I agree.

Hi,
An updated patch is here:
http://cr.openjdk.java.net/~jlahoda/8226585/webrev.02/
Changes in the update:
-added the dependency into the makefiles
-loosened the handling of essential preview APIs when
--enable-preview and @SuppressWarnings is applied - there is no
warning for the essential APIs (as there is no warning in such a case
for non-essential APIs). This is per the discussion in the CSR:
https://bugs.openjdk.java.net/browse/JDK-8231411
Any comments/feedback on this?
Thanks!

Oh, you are absolutely correct, the dependency is missing.
We need something like this inside "define SetupInterimModule":
$$(BUILD_$1.interim): $(COPY_PREVIEW_FEATURES)

I can’t see how the compilation is dependent on the copy being
finished. Since Erik contributed this it will probably be correct
:) but I’d appreciate an explanation on how this dependency is
guaranteed.
Or maybe I’m misunderstanding what this is supposed to do?

Thanks for the new code Erik!
A new webrev/patch that includes this better way of copying is here:

Any feedback is welcome!
Thanks,

Hello Jan,
The build change looks ok, but I would recommend this construct
for copying the file instead:
$(eval $(call SetupCopyFiles, COPY_PREVIEW_FEATURES, \
FILES :=
$(TOPDIR)/src/java.base/share/classes/jdk/internal/PreviewFeature.java,
\
DEST :=
$(BUILDTOOLS_OUTPUTDIR)/gensrc/java.base.interim/jdk/internal/PreviewFeature.java,
\
))
TARGETS += $(COPY_PREVIEW_FEATURES)
Then you automatically get all the corner case handling we have
implemented over the years for logging, making directories and
copying files. Your version is still correct for this case though.

Hi,
This is a continuation of Joe's patch from here:
https://mail.openjdk.java.net/pipermail/compiler-dev/2019-June/013498.html
APIs associated with preview features are split into two groups:
essential and non-essential. These are marked with an
JDK-internal annotation, PreviewFeature, and a tag in the
javadoc, @preview. The javac follows the PreviewFeature
annotation, and produces either warnings or errors for the
usages of such APIs. For the @preview tag, there is a taglet in
the JDK build that adds the content of the tag into the
documentation. The first part of the @preview's text goes into
the summary, the second part goes into the detailed description.
For build, a tricky problem is that the jdk.compiler module uses
the PreviewFeature annotation as well, but that is not in the
bootstrap JDK. So, for the intermediate langtools build, the
PreviewFeature annotation is copied from java.base.
Proposed webrev:

Javadoc with the change:
http://cr.openjdk.java.net/~jlahoda/8226585/docs.00/api/index.html
