Hi,
I came across this exception today :
java.lang.NullPointerException

In this bit of code in AbstractJSVGComponent r was being passed in as null
so it needs some null protection later on in the function.
protected void stopThenRun(final Runnable r) {
if (afterStopRunnable != null) {
// Have it run our new runnable, and not
// run the 'old' runnable.
afterStopRunnable = r;
return;
}
afterStopRunnable = r;
stopProcessing();
if ((documentLoader == null) &&
(gvtTreeBuilder == null) &&
(gvtTreeRenderer == null) &&
(svgLoadEventDispatcher == null) &&
(nextUpdateManager == null) &&
(updateManager == null)) {
Runnable asr = afterStopRunnable;
afterStopRunnable = null;
if ( asr != null ) { // added
asr.run(); // added
} // added
}
}
Best,
Tom
