Subject: WebView wv = new WebView(); throws an exception
Message-ID: <acc83746-c89a-419b-9234-25db5f62261b@dpsoftware.org>

Hi there,

I noticed recently that this code
WebView wv = new WebView();
throws an exception that creates no real problem but it is a bit annoyng.

The exception is thrown here:
class PropertyHelper {
 ? ? static boolean getBooleanProperty(String var0) {
 ? ? ? ? try {
 ? ? ? ? ? ? String var1 = System.getProperty(var0);
 ? ? ? ? ? ? return "true".equals(var1.toLowerCase());
 ? ? ? ? } catch (Exception var2) {
 ? ? ? ? ? ? return false;
 ? ? ? ? }
 ? ? }
}

If I manually set
System.setProperty("javafx.sg.warn", "true");

this exception is not thrown.

But why?
