I have a webstart application in which all the jars are signed (my own and third-party). When load it with Java7u25, I see error messages like the following in the Java console:
Missing Permissions manifest attribute for: http://example.com/webstart/application-jars/commons-beanutils-1.8.3.jar
Missing Codebase manifest attribute for: http://example.com/webstart/application-jars/commons-beanutils-1.8.3.jar
I read up on the changes in 7u25 here: http://blog.eisele.net/2013/06/java-se-7-update-25-release-notes.html
The note says to specify the Codebase attribute in the JAR's manifest at the time of building and have it match the Codebase in the JNLP file. How is this supposed to be setup to work for third-party jars like commons-beanutils which clearly don't have this manifest entry?
