Buggy source:
private boolean importTraces(){
  boolean success=false;
  IOverwriteQuery overwriteQuery=new IOverwriteQuery(){
    @Override public String queryOverwrite(    String file){
      return fOverwrite ? IOverwriteQuery.ALL : IOverwriteQuery.NO_ALL;
    }
  }
;
  FileSystemStructureProvider fileSystemStructureProvider=FileSystemStructureProvider.INSTANCE;
  for (  FileAndName traceToImport : fTraces) {
    try {
      if (fLinked) {
        createLink(fTargetFolder,Path.fromOSString(traceToImport.getFile().getAbsolutePath()),traceToImport.getName());
        success=setTraceType(traceToImport).isOK();
      }
 else {
        List<File> subList=new ArrayList<File>();
        subList.add(traceToImport.getFile());
        IPath path=fTargetFolder.getFullPath().append(traceToImport.getName());
        final File parentFile=traceToImport.getFile().getParentFile();
        ImportOperation operation=new ImportOperation(path,parentFile,fileSystemStructureProvider,overwriteQuery,subList);
        operation.setContext(getShell());
        if (executeImportOperation(operation)) {
          setTraceType(traceToImport);
          success=true;
        }
      }
    }
 catch (    Exception e) {
    }
  }
  return success;
}

Fixed version (ground truth):
