> Project: Harmony
> Type: Bug
> Components: Classlib
> Reporter: Richard Liang
> Assignee: George Harley
> Attachments: Modified_Manifest_MainAttributes.jar, harmony204.zip
>
> According to the new feature in JAR File Specification for java 5.0, .SF signature file which verifies the manifest has a new algorithm-Digest-Manifest-Main-Attributes entry which verifies the main attributes of the manifest. If the main attributes are tampered, harmony will not throw security exception while RI 5.0 will.
> The followging test case will demonstrate this issue.

> String path = URLDecoder.decode(this.getClass().getResource(".").getPath(),
> "UTF-8");
> String fileName = path + "/Modified_Manifest_EntryAttributes.jar";
> jarFile = new JarFile(fileName, true);
> JarEntry jarEntry = jarFile.getJarEntry("META-INF/MANIFEST.MF");
> try {
> jarFile.getInputStream(jarEntry);
