[jruby-user] Out of memory problem with JRuby-Complete

Hi,
I am working on a windows desktop application where I use JRuby for
developing the application and JRuby-Complete to package the application
in a jar. The application uses a fair number of external libraries -
including Qt for the user interface - but so far I have had no trouble
in running the packaged version once the JRuby version worked.
Recently I added functionality to the application to interoperate with
Microsoft Word using WIN32OLE. This works very nicely under JRuby using
the jruby-win32ole-0.8.5 gem, but when I run the same program using
JRuby-Complete, I consistently get the errormessage :

   "Can't QI object for IDispatch"

 Inspecting the error condition that leads to this message, it appears
that the interfacing software in the gem runs out of memory ( Windows
error: 0x8007000E ; E_OUTOFMEMORY).
I don't know if there is a difference in memory allocation policy
between the two JRuby implementations. I have experimented with
explicitly setting heap and stacksizes for JRuby-Complete e.g.

java -Xms256m -Xmx500m -Xss1024k -cp
lib\java\jruby-complete-1.7.13.jar;(other jars) org.jruby.Main
src\jruby_bootstrap.rb

But that made no difference to the error.

Any suggestions how I may solve this problem are very welcome
