OutOfMemoryError error when resizing JFrame with two JSVGCanvases

["Baron, Randy {PRG~Basel}" <RA...@Roche.COM>]

Hi,
   I was going to send this as a problem to the mailing list but (seemed
to) have solved it.  I thought it might still be useful for someone else
searching the archive though.
   The problem was getting an OutOfMemoryError when resizing a JFrame
that contained two JSVGCanvases inside two separate JScrollPanes.  It
turned out that the canvases were too big for the default jvm memory
allocation (each one 1000 x 5000).  The solution came from
http://www.cs.umd.edu/projects/hcil/jazz/list-archives/jazz-chat/0795.ht
ml where someone says that the JVM defaults to a memory allocation of
64M but can be increased at runtime through a command line parameter
like this: Java -Xmx256M (e.g. to 256M)
-Randy
