So we understand that the problem is the launcher and Jetbrains has to generate a new bundle following Oracles protocol. In looking through the latest release notes for IntelliJ IDEA 13 build 132.947 it looks to me like this was addressed under:
Package and Installation
||Bundle the required JRE into the AppCode application package
||For MacOSX installation with bundled jdk messages prompted to allow incoming connections are displayed
However it still doesn't work. IntelliJ still requires 1.6. I was able to get around this using the Unix version if any one is interested. Here's a blog post about it - http://duncandevore.blogspot.com/2013/11/intellij-on-mavericks-without-java-1.html.
Jetbrains please fix this!
