java-config -B <package-name> fails, because the new part of the classpath is added after the newline of the old classpath. This results in a "CLASSPATH=<oldclasspath>" line and a second line with ":<newclasspath>" in /etc/env.d/21java-classpath. See below for a complete example. I'm not a python expert, but I've included a patch for jc_options.py that works for me here.

Created attachment 37274 [details, diff] Patch for /usr/lib/python2.3/site-packages/java_config/jc_options.py
Is this still an issue? I cannot seem to reproduce this anymore, and this part of the code has been rewritten and improved since 1.2.11 (to be released). If it turns out to still bug you, reopen the bug with a use case.
