| ClassCastException or ClassNotFoundException [message #103209] |

I am trying to profile an application in Eclipse (Europa) and I keep
getting some exception like:
java.lang.ClassNotFoundException:
org.eclipse.hyades.logging.commons.FileLoggerFactory
or a ClassCastException telling me that FileLoggerFactory doesn't
implement org.apache.commons.logging.LogFactory
depending on where i am in my experiments to get it working. (btw these
exceptions are being thrown while it attempts to configure the logger
for Hibernate).
I have installed 4.4 with all prereqs to 3.3. The application launches
and runs correctly outside of TPTP.
Is there any specific plugins that i should make available in the launch
configuration or the running plugin?
How can I debug such a situation? Using launch profile doesn't support
debugging?
Any and all help would be very welcome.
Thanks
Alain

Eugene,
I ran many more tests to try to pinpoint the origin of the issue.
I started with a new install to see if our install method that relies on
the link/products directories could have anything to do with the issue.
Well, I am not getting the same behavior at all, except that it looks worse.
I have been getting this error whenever I 1st try to start a profiling
session:
Error occurred during initialization of VM
Could not find agent library on the library path or in the local
directory: JPIBootLoader
And now I just got another type of error:
The JVMTI agent org.eclipse.tptp.jvmti is not available. Make sure that
the librairies for the agent are available and that it is configured
properly.
I then tried to make some path changes and cleanup. This changed the
error messages, but it still kept failing.
I also tried running the sampleclient application, and that ran without
a glitch.
After all of this, I then downloaded the "all TPTP SDK" package and
overlaid it on my new install. After a clean restart, I have now stopped
getting any of the new errors and I am actually getting the exact same
errors as with my original install (ClassNotFoundException:
org.eclipse.hyades.logging.commons.FileLoggerFactory).
A couple more notes:
1) It seems that unless I do a connection test prior to launching the
profile launch, I get an error connecting to the agent.
2) Every time I start profile a launch configuration, it insist of doing
a "build before launch", even if I have just been running the same exact
launch config under debug seconds before. Furthermore, it is trying to
build other non-related workspace projects. Is that expected behavior?
Thanks for your help (I really need it here).
Alain

This problem still exists in TPTP 4.4.1. I've filed the bug 215438 here:
