pathelement triggers NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provider
Hello,
I'm posting this to dev instead of users because my best guess is that
this is a bug. But hopefully I'm wrong.
Consider the following target which runs a Java program MakeFoo.class:
<target name="foo">
<java classname="MakeFoo">
<classpath>
<pathelement location="."/>
</classpath>
<arg line="-o foo -d 'maken some foo'"/>
</java>
</target>
This generates the following exception:
$ ant foo
Buildfile: /some/path/to/build.xml
foo:

[java] Java Result: -1
Java and Ant versions are pretty much the latest:
$ java -version
java version "1.6.0_27"
Java(TM) SE Runtime Environment (build 1.6.0_27-b07)
Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)
$ ant -version
Apache Ant(TM) version 1.8.2 compiled on December 20 2010
And I know from using strace that Ant is actually using Sun's Java and
not openjdk.
If I remove the pathelement directive, the build works.
The com.sun.net.ssl.internal.ssl.Provider class is in
${JAVA_HOME}/lib/jsse.jar and that jar is present.
So it seems Ant does not load jsse.jar when using pathelement. Why?
I would appreciate it if someone has a work-around for me. I need to
specify a bunch of jars in the classpath using fileset and once I do
that I need to add '.' so that the program itself is in the classpath.
But once I do this pathement triggers the jsse.jar problem. And
obviously I don't want to add a jsse.jar dep in the build.xml. So I'm
stuck. Please help.

Huh? I must have misread your original post, sorry.
<pathelement> certainly doesn't require jsse.jar, not much in Ant would
do (the SSH tasks and the mail layer if TLS is used). It must be your
code that requires it.

Hi Stefan,
Adding that pathelement had no effect. I still get precisely the same error.
I would argue that if pathelement requires jsse.jar, it should
automatically include it in the classpath just as it does rt.jar.

I ended up just copying jsse.jar into my jars directory which is part
of the classpath using a fileset so that the issue would at least no
pollute my build.xml. Of course when I update Java this could break.
But I could not think of another way to do it.
Thanks anyway. I just posted for posterity mostly.

Probably not.

If you don't specify the <classpath> explicitly your Java process runs
with the same CLASSPATH that is used by Ant internally - which includes
jsse.jar.
If you specify it, then you only get what you have asked for (unless you
fiddle with the build.sysclasspath property), or close to it. I think
it should work if you explicitly add
<pathelement path="${java.class.path}"/>
if you don't like hardcoding jsse.jar (which you could address relative
to ${java.home}).
