At this moment we have a problem: RContext#resolve can go into stackoverflow:

    at net.ranides.assira.reflection.impl.RContext.resolve0(RContext.java:74)
    at net.ranides.assira.reflection.impl.RContext.resolve(RContext.java:62)
    at net.ranides.assira.reflection.impl.RContext.resolve0(RContext.java:74)

It is hard to say, what is cause of the problem, but it can be reproduced in AClassTest#testRecursiveString

At this moment we inserted workaround inside AClass#toString, but it causes that nested types can't be converted to correct string.

If we declare parameterized type Something<T> and then declare nested type Something<Something<Something<T>>>, we have infinite recursion.

Somewhere under the hood, toString converts parameters to strings. To do so, it has to create parameters list first. Parameter list is created lazily, and every parameter creates result using context:typeinfo.

typeinfo calls resolveTV

IContext somewhere
