I have a qestion about jarsigner's -verify option. The tooldoc says that it will verify the given jar file whether it has been tampered or not. What happen if I change the jar content and sign again with my private key. jarsigner will report jar is still intact. If that the case, what is the use of this option or I'm missing something here?

thank you.

IT allows to check if your jar hasn't been corrupted seen it was signed.
Try to sign your jar, then update by changing one class file, and try to verify it, you'll got an exception.
