A primitive type as parameter for generic type and JavassistTypeSolver

[izebit]

When we try to get fields for classes from jar archive we will have UnsolvedSymbolException. It happens if a field is parametrized and its generic type is primitive.
For example:

We have the class:

public class ClassWithFields {
    private List<byte[]> genericPrimitiveArrayField = new ArrayList<>();
   ...
}

and we want to get fields from this class:

((JavassistClassDeclaration) anotherTypeSolver.solveType("com.github.javaparser.test.ClassWithFields")).getAllFields().forEach(e->e.getType());

After execute the code, which is above, we will see the next stacktrace:

Unsolved symbol : byte[]
UnsolvedSymbolException{context='null', name='byte[]', cause='null'}
