Ocaasionally SQL Developer comes in a state where CPU usage is 50% (on a dual core machine) and according to jvisualvm "Background Parser" and InsightThread is using the CPU, and only these two.
This continues also after closing all connections.
I don't really know what lead up to this.

This temporary high CPU usage is most likely related to the size of your SQL History. Look for the preference that controls the size limit in Tools | Preferences | Database | Worksheet.
