Jim Lim commented on AVRO-1315:
-------------------------------
It appears that {{Symbols#hasErrors}} will get into a infinite recursion if the
validator is applied on an array or map. For example,
{code:title=test.java|borderStyle=solid}
private static final Schema mpSchema = new Schema.Parser().parse(
"{\"name\": \"mapType\", \"type\": \"map\", \"values\": \"string\"}"
);
SchemaValidator validator = new
SchemaValidatorBuilder().canReadStrategy().validateAll();
validator.validate(mpSchema, ImmutableList.of(mpSchema));
{code}
will cause {{Symbols#hasErrors}} to get stuck inside the `REPEATER` case, since
the repeater symbol refers to itself inside its production array. I found a fix
that uses a TreeSet to maintain a collection of visited symbols, and will
submit a patch shortly.
