Hi Philipp, I've read all the src/ files.
ManifestDigester.java: 140 if (!findSection(0, pos)) throw new IllegalStateException( 141 "ManifestDigester failed to create " + MF_MAIN_ATTRS + " entry"); This is a behavior change, although it might be the correct choice. I think you will at least need a CSR to publicly discuss about it. If the manifest has something but not ends with new line, is it possible to read them? If the manifest is just empty, is it possible to create an Entry with no Section? JarSigner.java: 696 mfCreated = true; Unnecessary anymore. 723 String zeNameUp = ze.getName().toUpperCase(Locale.ENGLISH); 724 if (SignatureFileVerifier.isBlockOrSF(zeNameUp)) { 725 if (!zeNameUp.startsWith(SignatureFile 726 .getBaseSignatureFilesName(signerName))) { 727 wasSigned = true; 728 } 729 } You added a new check. Do you mean if the signer is the same then the SF will be rewritten anyway and there is no need to retain old MANIFEST.MF bytes? 900 if (ze.getName().startsWith(SignatureFile 901 .getBaseSignatureFilesName(signerName))) { 902 if (handler != null) { 903 handler.accept("updating", ze.getName()); 904 } 905 continue; 906 } It looks you are dealing with a use case that a file was signed with alias=A having an RSA key, and now you re-sign it with alias=A this time having an EC key, and you want to drop the A.EC file. Right? What if there is a file A.XYZ there? Can we add an additional check isBlockOrSF(ze.getName())? I admit no one is likely to store an A.XYZ there. I'll read the tests.
