- JDK 8 jar signer does not work with a JDK 9 created keystore - JDK 8 signed jar with JDK 8 created keystore is not the same size as JDK 9 signed jar with JDK 9 keystore - JDK 8 signed jar with JDK 8 created keystore is not the same size as JDK 9 signed jar with the same JDK 8 keystore
The default keystore type in jdk9 is pkcs12. I guess this is why jarsigner in jdk8 does not recognize it.
As for the size, I guess the default signature algorithm or key size might not be the same, say, SHA1withRSA -> SHA256withRSA or 1024 to 2048.
