The PTBKey looks complicated and errorprone (updating hashCode on an Element in a HashMap). Let's find out what was really slow and then see if we find a better solution for "linear effort during lookup" (https://bugs.eclipse.org/bugs/show_bug.cgi?id=434326#c2) partial revert commit 510e796 (Bug 434326 - Slow compilation with a significant amount of generics) keeps binary search in TypeSystem.cacheDerivedType(TypeBinding keyType, TypeBinding derivedType)
