Please review: 7194005: (launcher) needs to be enhanced for 64-bit jar file handling

[Kumar Srinivasan]

Hi Sherman, 

Thanks for the review, I will make that test conditional. 

As for using the entry points I looked at it, the issue 
is that java_util_zip reading code is dependent on jni and the jvm 
loaded, but here in the launcher we are still early in the 
launch process and we do not yet have a functional jvm 
running. 

So definitely your suggestion is a good future project and we 
may have to refactor the zip code to be jvm neutral. 

Thanks 

Kumar

Hi Kumar,
