This is very strange… I started seeing this error pop up. I never saw it
before… I even reverted my code back a few days when the error wasn’t
present but it’s still there! What’s really weird is that it appears to
still function fine after this. Anyone know anything about this?
java.lang.NoClassDefFoundError:

THE LINE THAT CAUSED IT:
PDVisibleSignDesigner visibleSig = *new
*PDVisibleSignDesigner(document.getAbsolutePath(),
image, 1);
THE ERROR:
Could not instantiate SVGImageReader (missing support classes).
