This is the piece of code involved : "try { // create an instance of the model model = solrResourceLoader.newInstance( className, LTRScoringModel.class, new String[0], // no sub packages new Class[] { String.class, List.class, List.class, String.class, List.class, Map.class }, new Object[] { name, features, norms, featureStoreName, allFeatures, params }); if (params != null) { SolrPluginUtils.invokeSetters(model, params.entrySet()); } } catch (final Exception e) { throw new ModelException("Model type does not exist " + className, e); }"
I admit it is generic and contains even a catch "Exception" clause, but wasn't it logging the stacktrace ? Just out of curiosity, how was the entire stacktrace ? This may help to improve it.
