{{PackagedProgram.extractContainedLibraries}} tries to replace all path separators using the platform-dependent {{File.separateChar}}, however the path separator for jars (and zips for that matter) is always {{/}}.

{code}
final JarEntry entry = containedJarFileEntries.get(i);
String name = entry.getName();
name = name.replace(File.separatorChar, '_');
{code}
