When classes of parameters are not yet loaded, it is impossible to determine whether or note the classe is parametric

[LeoDefossez]

See class JDIToTraceConverter

private List<TraceParameter> createParametersFor(Method method) {
		List<TraceParameter> res = new ArrayList<>();
		try {
			// trying to obtain the arguments information
			Iterator<LocalVariable> ite = method.arguments().iterator();

			while (ite.hasNext()) {
				res.add(newParameterFrom(ite.next()));
			}
		} catch (AbsentInformationException e) {
			// arguments name could not be obtained
			// Since the name are not obtainable just log the parameters types
			// This happen when classes are not yet loaded or with native methods
			Iterator<String> ite = method.argumentTypeNames().iterator(); <<------------------- Here we only have String
			while (ite.hasNext()) {
				res.add(this.newParameterFrom(ite.next()));
			}
		}

		return res;
	}

A solution to resolve it could be to create a event on the loading of the class and creating the type at the moment it will load.
