RE: [Cobertura-devel] Out of Memory Exception

[Mark D. <Mar...@sa...>]

You could try passing -Xmx512m to ant.  I have a feeling this won't =
work, but it's worth a shot.  The ant tasks start a new JVM to do the =
instrumentating, and I don't think we have a way to set the max memory =
size for that JVM (but there is a chance this max memory size is =
inherited from the ant JVM).

If the above does not work, you could try calling the instrument class =
directly, with something like
java -Xms512m -cp cobertura.jar net.sourceforge.cobertura.coverage.Main =
-d C:\output\directory C:\compiled\classes\directory

At least, I think that's right...
