Description Jaroslav Tulach 2015-04-13 02:07:29 UTC 
I left the IDE running overnight and now I am trying to find out why it is too slow. It is allocating 5MB per second. When I tried to self-profile, it turned out that are at least ten threads trying to reead RSS feed and the log is full of errors like:

SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Line number:1
SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Column number:1
SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Public ID:null
SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: System ID:null
SEVERE [org.netbeans.modules.welcome.content.RSSFeed]: Error message:Premature end of file.

So I guess the slowness and these failures must be related.

Trying to fix this by cancelling the running task that loads the feeds when there is a SAXException.
