Incorrect SymLink causes build failures in other packages

[TJ]

[Impact]

Due to an incorrect symlink created in the package, using this Java library with another Java application (or, in this case, building Gradle) will fail.

[Test Case]

The simplest would be to use this library in some way. The only application that I personally know of that uses this library is Gradle. ("apt-cache rdepends libwerken.xpath-java" says that this library is also used in velocity.)

[Regression Potential]

Minimal. This is fixing a symlink created by the package, and (at least as of Vivid) this package is used in only one other package.

[Original Description]

This affects Trusty and possibly others. I hit it whilst backporting JavaFX (openjfx):

Execution failed for task ':graphics:classes'.
> Could not list contents of '/usr/share/java/werken.xpath.jar'.

The package installs an incorrect symbolic link when trying to alias the alternative hyphen and dot-separated names, causing packages looking for "/usr/share/java/werken.xpath.jar" to fail to build.

$ ls -l /usr/share/java/werken*
-rw-r--r-- 1 root root 76418 Jan 27 2012 /usr/share/java/werken-xpath-0.9.4.jar
lrwxrwxrwx 1 root root 22 Jan 27 2012 /usr/share/java/werken-xpath.jar -> werken-xpath-0.9.4.jar
lrwxrwxrwx 1 root root 22 Jan 27 2012 /usr/share/java/werken.xpath.jar -> werken.xpath-0.9.4.jar

The manual work-around is to fix the link:

$ sudo ln -fs /usr/share/java/werken-xpath-0.9.4.jar /usr/share/java/werken.xpath.jar

$ ls -l /usr/share/java/werken*
-rw-r--r-- 1 root root 76418 Jan 27 2012 /usr/share/java/werken-xpath-0.9.4.jar
lrwxrwxrwx 1 root root 22 Jan 27 2012 /usr/share/java/werken-xpath.jar -> werken-xpath-0.9.4.jar
lrwxrwxrwx 1 root root 38 May 15 00:42 /usr/share/java/werken.xpath.jar -> /usr/share/java/werken-xpath-0.9.4.jar

The verification of the Stable Release Update for werken.xpath has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

[Ubuntu Foundations Team Bug Bot (crichton)]

The fix for this bug has been awaiting testing feedback in the -proposed repository for precise for more than 90 days. Please test this fix and update the bug appropriately with the results. In the event that the fix for this bug is still not verified 15 days from now, the package will be removed from the -proposed repository.

[Martin Pitt (pitti)]

The version of werken.xpath in the proposed pocket of Precise that was purported to fix this bug report has been removed because the bugs that were to be fixed by the upload were not verified in a timely (105 days) fashion.
