Description of problem:
I am working with a fresh install of Eclipse 3.1.2 and CDT from fedora core 5
RPMs, and with subclipse added using the standard update procedure.  This
installation worked for several hours without problems on 5/23, building a
moderately large C/C++ project and updating SVN repositories.  The following
day, after installing updates using yum, this installation fails after startup,
during the C/C++ indexing process with the following messages:

java.lang.ClassCastException:
