java - Adding signature to jar file prevents it from being loaded -

-

i having problem adding second signature .jar file causes trouble in combination code has 1 of them.

background: have application signed expired certificate. has starter can update downloading new versions of .jar files , placing them in front of existing ones onto classpath.

we got new certificate , sign new starter , updates both keys. unfortunately old applications refusing startup:

  • the starter (signed old cert) builds classpath.
  • then calls method class ("stendhal") jar signed both certs
  • this method loads class ("loguncaughtexceptionhandler") jar signed old cert.

securityexception: class "games.stendhal.client.loguncaughtexceptionhandler"'s signer information not match signer information of other classes in same package

could not arrange download new version of jar loguncaughtexceptionhandler, signed new cert? if not, don't think you're going find suitable resolution issue.
