Bug#764376: ant: Removing Xerces breaks logback use in Sonar

[Tim Pizey]

Package: ant
Version: 1.8.2-4
Severity: normal

Dear Maintainer,

The sonarqube ant task uses logback, which in turn uses XML to define
its configuration.

The task definition assumes the presence of xerces, an assumption
which holds for the Apache version of ant.

The Debian version splits out Xerces and assumes that it can be fed back
in through the CLASSPATH.

See https://github.com/dankamongmen/sprezzos-world/blob/master/packaging/ant/debian/patches/0003-add-Xerces-from-Debian-s-path.patch

I have created a minimum project which illustrates the problem at
https://github.com/timp21337/sonar-ant-fail

The problematic code is given here:
https://github.com/SonarSource/sonar-runner/blame/master/sonar-runner-batch/src/main/java/org/sonar/runner/batch/IsolatedLauncher.java

yours sincerely
Tim Pizey

Hi Tim,

Thank you for the report. What is the expected output of your test? I
ran sonar-ant-fail and didn't see any error with ant 1.9.4 currently in

You have Java 6, and I ran the test with Java 8u40. It also works with
Java 7u65, but I got the same error after switching to Java 6.

OpenJDK 6 has been removed from Jessie, so the issue only happens if you
install the Oracle JDK. Do you need a fix for Squeeze or are you able to
upgrade to Java 7?
