I'd like to add the point that java (.exe) is simply a wrapper for libjli 
(jli.dll). In 7/8 the custom launcher uses this same interface to launch the 
application, so it  technically already uses the same code to launch. The other 
features of the custom launcher *cannot* be replicated by the SE launcher 
without massive changes to JLI and the SE launcher code.

Having said that... it's not entirely unreasonable to think that some useful 
parts of the launcher could be contributed to JLI. But that brings a host of 
other issues to the table, namely dealing with getting changes into OpenJDK and 
convincing the guys on the JDK tl team that such changes are necessary. By 
keeping the launcher code in fx packager, we keep the noise to a minimum which 
allows us to be able to be more flexible and responsive to developer demands. 
Once the product is mature enough, maybe we can revisit this.
