[Bug 59860] New: org.apache.tools.ant.taskdefs.RmicAdvancedTest
failed with JDK 9 changes for modularization
https://bz.apache.org/bugzilla/show_bug.cgi?id=59860
Bug ID: 59860
Summary: org.apache.tools.ant.taskdefs.RmicAdvancedTest failed
with JDK 9 changes for modularization
Product: Ant
Version: 1.9.7
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Core tasks
Assignee: notifications@ant.apache.org
Reporter: felix.yang@oracle.com
org.apache.tools.ant.taskdefs.rmic.SunRmic.java tries to instance
sun.rmi.rmic.Main. But because of JDK 9 changes for modularization (project
Jigsaw), sun.rmi.rmic.Main is not visible by default. It has been refactored
into a system module named jdk.rmic and package sun.rmi.rmic is not exported.
See
http://hg.openjdk.java.net/jdk9/dev/jdk/file/4729dcda8ea8/src/jdk.rmic/share/classes/module-info.java
So tests in RmicAdvancedTest will fail with ClassNotFoundException. This can be
workaround by specify following arguments to java
"-addmods jdk.rmic -XaddExports:jdk.rmic/sun.rmi.rmic=ALL-UNNAMED"
or
"-addmods ALL-SYSTEM -XaddExports:jdk.rmic/sun.rmi.rmic=ALL-UNNAMED"
These Jigsaw changes are not finalized. The workaround above can be changed
later.

--- Comment #4 from Felix Yang <fe...@oracle.com> ---
For the issue of "rmic -Xnew", please refer to following two bugs:
1. https://bugs.openjdk.java.net/browse/JDK-8129341
It commented "The -Xnew option was never documented and was never supported.
Any dependencies on -Xnew should be removed. Closing this as Not an Issue."
2. Remove rmic -Xnew, https://bugs.openjdk.java.net/browse/JDK-8146299

Felix, is there some special handling of com.sun.tools.javac.Main expected or
will <javac> be broken soon as well?

Fixed with git commit fdfebe8
note that rmic -Xnew causes strange error messages and still fails (I'm sure
I've reported this every time I tested any jdk9 build).
I'm worried about "com.sun.tools.javac.Main" used in <javac> and
"com.sun.tools.javah.oldjavah.Main" used in <javah> - in particular since we
don't seem to have a decent test coverage for the later.

The test failing is only a symptom, the rmic task itself won't work unless you
add the workarounds when starting Ant.
Apart from skipping the test when running on JDK9+ the proper fix probably is
to make "forking" the default implementation on JDK9+ and document that "sun"
won't work for JDK9+. And probably detect a constellation like this at runtime
and provide a useful error message.
