> Some areas in Wicket code do expensive creation of WicketRuntimeException and then just ignores it.
> The most common case is :
> at java.lang.Throwable.fillInStackTrace(Native Method)
> at java.lang.Throwable.<init>(Throwable.java:218)
> at java.lang.Exception.<init>(Exception.java:59)
> at java.lang.RuntimeException.<init>(RuntimeException.java:61)
> at org.apache.wicket.WicketRuntimeException.<init>(WicketRuntimeException.java:49)
> at org.apache.wicket.MarkupContainer.getMarkupType(MarkupContainer.java:476)
> at org.apache.wicket.markup.DefaultMarkupCacheKeyProvider.getCacheKey(DefaultMarkupCacheKeyProvider.java:85)
> at org.apache.wicket.markup.MarkupCache.getMarkup(MarkupCache.java:274)
> at org.apache.wicket.markup.MarkupFactory.getMarkup(MarkupFactory.java:218)

> at org.apache.wicket.markup.html.panel.PanelMarkupSourcingStrategy.getMarkup(PanelMarkupSourcingStrategy.java:70)
> at org.apache.wicket.MarkupContainer.getMarkup(MarkupContainer.java:456)
> at org.apache.wicket.Component.getMarkup(Component.java:734)
> at org.apache.wicket.MarkupContainer.add(MarkupContainer.java:173)
> ...
> and is ignored in MarkupContainer#add(). 
> Such an exception is created for every component which is added in the constructor of another component (in contrast to onInitialize() where the markup will be available).
