JDK-4244499 - ZipEntry() does not convert filenames from Unicode to platform
Description

Name: dc32491			Date: 02/06/2001


According to JAR File Specification <http://java.sun.com/j2se/1.3/docs/guide/jar/jar.html>, JAR file is just a zip file that contains an optional META-INF directory. The actual implementation in JDK is using UTF8 encoding for file names. That is not compatible with Zip file format, even if it is a better approach.
This incompatibility causes that file names are corrupted while using other Zip utility program such as WinZip to open a JAR file.
It would be nice if SUN can update JAR file specification by describing explicitly that file names in JAR files are UTF8 encoded.

Comments
EVALUATION The java.util.jar package specification has been updated since 1.4.2 with the following wording "n JAR files, all file names must be encoded in the UTF-8 encoding." The issue of "This incompatibility causes that file names are corrupted while using other Zip utility program such as WinZip to open a JAR file." has been addressed in #4244499. Closed as "not reproducible" (since 1.4.2)
