Description Gabriel BARBIER CLA 2010-07-13 04:57:16 EDT 
Hello, 

During the discovery of a java project, I got the following exception with the latest discoverer. However, with previous version of discoverer, I was able to get the java model.

eclipse.buildId=I20100603-1500
java.version=1.6.0_20
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=fr_FR
Framework arguments:  -product org.eclipse.epp.package.modeling.product
Command-line arguments:  -os win32 -ws win32 -arch x86 -product org.eclipse.epp.package.modeling.product

This is a continuation of log file D:\MoDisco\perfs\.metadata\.bak_9.log

Hi Gabriel,

could you provide a project sample for getting this error ? Please indicate also the existing compilation errors (incomplete classpath ...) on this project when launching the discovery, as the problem might be caused by unresolved types.
