EVALUATION Closed as NOT-A-DEFECT. Unlike a zip file, the jar file's entry names must be UTF-8 encoded, therefore it should be maintained by the jar/jarsigner command only for safety.
30-06-2009
EVALUATION New constructor(s) ZipFile(...,Charset cs) have been intorduced in JDK7 to address non-UTF-8 file name/comment issues described in #4244499. Transfer the bug back to security to decide how to use the newly introduced constructor to solve this particular issue in jarsigner.

EVALUATION This will be addressed in Dolphin, along with other character encoding / zip file related bugs.

EVALUATION The problem here goes down to -- ZipFile zf =.... for (Enumeration enum_=zf.entries();enum_.hasMoreElements();) { ZipEntry ze = (ZipEntry)enum_.nextElement(); InputStream istream = zf.getInputStream(ze); istream is null when ze contains the German umlaut
15-08-2005
EVALUATION This functionality appears to be maintained by the security team in the classes_security sub_category; reassigning.
