[Bug 1235143] [NEW] libcommons-lang-java is incorrectly marked as a dependency of libcommons-cli-java

[picomancer]

Public bug reported:


I'm writing a Java program and I want to use Apache Commons command line parser.  I install libcommons-cli-java like this:

$ sudo apt-get install libcommons-cli-java

...
The following extra packages will be installed:
  libcommons-lang-java
...

But none of the code in libcommons-cli-java requires libcommons-lang-
java to run.  You can easily see this by doing the following:

    mkdir temp
    cd temp
    jar xvf /usr/share/java/commons-cli-1.2.jar
    find . -type f | xargs strings | grep lang | grep -v java/lang
    find . -type f | xargs strings | grep org.apache.commons.lang

(NB class names are actually in class files as org/apache/commons/lang,
but the dot character is actually a wildcard in grep, so this command
actually does search for what I claim it searches for)

You can see the only occurrence of the string "lang" is in the license;
the class files only contain references to java.lang (Java language
builtins).  There is no mention of org.apache.commons.lang (the Java
package provided by libcommons-lang-java)!

Someone should probably report this bug to Debian, since Debian seems to
suffer from this problem as well -- see http://packages.debian.org/sid
/libcommons-cli-java
