On October 15, 2013, Oracle released Java 7 Update 45. When an end user loads the signed ParaChat Java chat client after updating their Java version to Java 7 Update 45, they may notice a new yellow warning box within the Do you want to run this application? dialog. The yellow warning box contains a message that says This application will be blocked in a future Java security update because the JAR file manifest does not contain the Permissions attribute:
note that this is a known issue that will be resolved on October 16,
2013, when the ParaChat JAR file manifest is updated to contain the
Permissions attribute. Once this ParaChat JAR file has been updated,
the yellow warning box will no longer display in the Do you want to run this application? signed Java chat client dialog.
