What is package cache in a jar file

[HS1]

Hello all
I know that a jar file is considered as zip file. I see a Jar file that has
a package cache. Could you please tell me the purpose of this "package" or
locate a tutorial about content of a jar file...
Many thanks

Do you mean the jar index? AFAIR that one is there since Java 1.3.

The Jar file format is documented in the JDK documentation. You did
download the JDK documentation when you fetched the JDK, didn't you?

JBuilder (Maker/compiler) creates a folder 'package cache' when building
source files, I think it originates from there.
I don't know if other make utilities do that, but it's probably from
JBuilder.
