[Dojo-interest] Exception in ShrinkSafe?

[Ryan Moore]

Your file is too big for the default Java memory settings, you have to
change a couple of command-line switches to expand the available memory:

 

java -Xmn100M -Xms500M -Xmx500M -jar ~/shrinksafe/custom_rhino.jar -opt
-1 -c input.js > output.js 2>&1

Subject: [Dojo-interest] Exception in ShrinkSafe?

 

Hello. Great work on the project so far.

 

I'm currently working on a project with just over 3MB of Javascript.
Obviously, this is quite large, so we were hoping to use Dojo's
ShrinkSafe to make it as small as possible. I tested ShrinkSafe with a
subset of our project's functionality and it all worked fine. However,
when I try to use ShrinkSafe on our entire code base, I ShrinkSafe
throws the following exception:

 

Exception in thread "main" java.lang.IllegalArgumentException: out of
range index

 The process I'm following is I'm rolling all our Javascript into one
file, checking the Javascript still works, then running ShrinkSafe from
the .jar file with the directions provided at the following page:
http://dojotoolkit.org/docs/compressor_system.html#about-the-author . 

 

I have little idea at the moment what the problem might be, so I'm going
to go through our Javascript to see if I can discover if any of our code
is the problem. However, I was wondering if there was anyone with
suggestions as to what the problem may be.

 

Any suggestions, anyone?
