I am trying to optimize my RSL-files size using the optimizer-tool inside Flex SDK, following this guide:  
[http://livedocs.adobe.com/flex/3/html/help.html?content=rsl\_07.html](http://livedocs.adobe.com/flex/3/html/help.html?content=rsl_07.html)

I first tried with a small RSL \*(1kb) \*and it worked perfectly, however!  
When I tried it on my real RSL-file, I get an error message from Java saying that it’s out of memory.  
I have changed the maximum heap size for Java, I managed to get it up to \*\*1566mb \*\*maximum  
and it’s still running out of memory!

1566mb is maximum on the 32-bits java it seems, and Flex doesn’t support 64-bits java.

I really want to keep the RSL in just one file! \*(If I split it up in two, it should work)  
\*Thanks in advance,
