I have a large project (almost 2,000 Java files), and sometimes jde-xref works in finding callers, sometimes it doesn't. It seems to be on a per-class basis; i.e. any method in class A I can list callers, but in class B no callers are found for any methods.
Looking at the xrefdb directory, it looks like the database was created correctly... i.e. the appropriate -caller file looks like it has the correct entry for class B, with all its methods. Any ideas what could be going on? Raul
