Launch4j vs exe4j

I am using launch4j to build spark.exe, but it still causes issues vs. the exe4j version.

Most notably, pinning does not work in Windows 7. The spark window comes up separately from the pinned icon. Probably because it uses javaw to run, or something.

As a side note, how does one go about using exe4j to build? I could not find any targets in the source to build using exe4j.

I see, I have to use install4j to get the exe4j build.
