JARs affected by these new restrictions should be replaced or re-signed with stronger algorithms. =MD2, MD5, RSA keySize < 1024, DSA keySize < 1024, SHA1 denyAfter WARNING: The jar will be treated as unsigned, because it is signed with a weak algorithm that is now disabled by the security property: Signature algorithm: SHA1withRSA (disabled), 2048-bit key

To determine if your signed JARs are affected by this change, run jarsigner -verify -verbose -certs on the signed JAR, and look for instances of 'SHA1' or 'SHA-1' and 'disabled' and a warning that the JAR will be treated as unsigned in the output. This exception may be removed in a future JDK release. Any JAR signed with SHA-1 algorithms and timestamped prior to Januwill not be restricted.To reduce the compatibility risk for JARs that have been previously timestamped, there is one exception to this policy: These restrictions also apply to signed JCE providers. It also applies to the signature and digest algorithms of the certificates in the certificate chain of the code signer and the Timestamp Authority, and any CRLs or OCSP responses that are used to verify if those certificates have been revoked. This applies to the algorithms used to digest, sign, and optionally timestamp the JAR. JARs signed with SHA-1 algorithms are now restricted by default and treated as if they were unsigned. Warning: The links /usr/lib/jvm/default and /usr/lib/jvm/default-runtime should always be edited with archlinux-java.Security-libs/curity ➜ Disabled SHA-1 Signed JARs
