JVM crashes are pretty rare; normally I curse for a while and reinstall java / jai / imageio etc. In this case the DLL is the C runtime; and has a history of getting messed up at the windows registry level.
Still it sounds like java now passes some work over to direct draw; and thus we must be getting near the edge of floating point or double accuracy in order to make the drawing routines unstable :-) A couple things to do: - do your scaling on the geometry; before making a shape - test that the geometry is valid; before making a shape - change how you do a deep zoom; rather than depend on the differences between floating point values; scale your geometry up and then do not zoom in as far - experiment with the java command line option to turn off direct draw acceleration (http://java.sun.com/j2se/1.5.0/docs/guide/2d/flags.html) and see if the problem goes away Jody On Wed, Apr 8, 2009 at 11:38 PM, Carsten Ehbrecht <[email protected]> wrote: > Hi, > > i have the following problem with the streaming renderer in gt-2.5.3: > > * Starting the StreamWidgetsDemo > * just loading a single line geometry (shapefile) > * i zoom into this line over and over again > * when i'm too deep the rendering takes long and then the jvm crashes with a > stack overflow exception :( > > Do you know this problem already? > > I have attached the crash report > > Cheers, > Carsten > > ------------------------------------------------------------------------------ > This SF.net email is sponsored by: > High Quality Requirements in a Collaborative Environment. > Download a free trial of Rational Requirements Composer Now! > http://p.sf.net/sfu/www-ibm-com > _______________________________________________ > Geotools-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/geotools-devel > > ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
