JarIndex not following the specification

[Tobias Stadler]

Hello everyone,

According to https://docs.oracle.com/en/java/javase/17/docs/specs/jar/jar.html, sections in META-INF/INDEX.LIST are divided by blank lines.

The write method of jdk.internal.util.jar.JarIndex does write those blank lines. But the read method begins a new section whenever it sees a line that ends with .jar. Does anybody know why JarIndex#read does not follow the specification? Is this a bug?

E.g.

some.jar
META-INF
META-INF/another.jar
org

Will be be read as two sections instead of just one. Also the package org will be mapped to META-INF/another.jar instead of some.jar.
