When trying to validate a record which is recursively defined:
{code}
    Schema record = Schema.createRecord("List", null, null, false);
    record.setFields(list(new Schema.Field("head", 
Schema.create(Schema.Type.INT), null, null),
      new Schema.Field("tail", record, null, null)));
{code}
then schema validation
{code}
new SchemaValidatorBuilder().canReadStrategy().validateAll().validate(record, 
asList(record));
{code}
fails with StackOverflowError:
