           Summary: OutOfMemory error when triggering set element rapidly
           Product: Batik
           Version: 1.7
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: GVT
        AssignedTo: batik-dev@xmlgraphics.apache.org
        ReportedBy: frodef@stud.cs.uit.no


The SVG below, when rendered in squiggle, triggers a bug in Batik that causes
the jvm to grab 100% CPU (squiggle becomes unresponsive) and emit an infinite
number of "java.lang.OutOfMemoryError: Java heap space" messages in the console,
when the mouse is rapidly and repeatedly moved over the FOO and BAR buttons for
a few seconds (something like 5-10 seconds).

This is with the current (as of a few minutes ago) development version of Batik,
on windows XP and jdk 1.5.0_06.
