Attached is a patch that fixes the problem. OK for a new 'java-work'
branch based off of the right maint-based commits (as to make new
tests like 'java-extra.test' and `java-noinst.test' available)? We
can decide at a later date whether this branch has to be merged into
maint or into master only.
I'll push in 72 hours if there is no objection.
Regards,
Stefano

Subject: [PATCH] java: allow both dist_JAVA and nodist_JAVA in the same Makefile.am
Fixes automake bug#8434.
* automake.in (handle_java): Strip `dist_' and `nodist_' from
the given prefix. Define a new internal Makefile variable
`am__java_sources'. Related adjustments.
* lib/am/java.am (JAVAC, JAVAROOT, CLASSPATH_ENV): Define only the
first time this am file is processed.
(class%DIR%.stamp): Stamp file renamed ...
(class%NDIR%.stamp): ... to this, so that the `dist_' and `nodist_'
prefixes are stripped from the name of the stampfile. Adjust
declaration of dependencies by using the new automake-generated
internal variable `$(am__java_sources)'. In the rule, use `$@'
as the name of the target, rather than hard-coding it.
* tests/java.test: Update and extend.
* tests/java-no-duplicate.test: New test.
* tests/java-mix-dist-nodist.test: Likewise.
* tests/java-compile-and-install.test: Likewise.
* tests/java-clean.test: Likewise.
* tests/java-sources.test: Likewise.
* tests/Makefile.am (TESTS): Update.
