           Summary: Bad classloader used to load particular java compiler
           Product: Ant
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: sebastien.chassandebarrioz@rd.francetelecom.com


When ant compilers are used under eclipse, the loading of the eclipse compiler
(org.eclipse.jdt.core.JDTCompilerAdapter) fails. The problem comes from the
classloader used to load the class.  The loading is done by the method 
org.apache.tools.ant.taskdefs.compilers.CompilerAdapterFactory.resolveClassName(String).
The used classloader is the System classloader. Below you will found the patch
of the class. My patch try to use the classloader of the current class instead
of the system classloader.
