Buggy source:

{
    store.setDefault(Preference.Common.srcMainPath,"String_Node_Str");

Fixed version (ground truth):
@Override public void initializeDefaultPreferences(){
  IPreferenceStore store=Activator.getDefault().getPreferenceStore();
{
    store.setDefault(Preference.Common.srcMainPath,"String_Node_Str");
    store.setDefault(Preference.Common.srcTestPath,"String_Node_Str");
  }

    store.setDefault(Preference.TestClassGen.enabled,true);
    store.setDefault(Preference.TestClassGen.junitVersion,Preference.TestClassGen.junitVersion3);
    store.setDefault(Preference.TestClassGen.classToExtend,"String_Node_Str");
    store.setDefault(Preference.TestClassGen.usingJunitHelperRuntimeLib,false);
  }

    store.setDefault(Preference.TestMethodGen.enabled,true);
    store.setDefault(Preference.TestMethodGen.includePublic,true);
    store.setDefault(Preference.TestMethodGen.includeProtected,true);
