[Bug]: Type reference building logic fails within lambda bodies

[lukebemish]

Describe the bug

Something seems to go wrong with type reference parsing within method bodies when extends is involved. The following fails with the included stack trace:

Launcher.parseClass("""
    public class Test {
        public static void test() {
            final Supplier<Object> supplier = () -> {
                final Supplier<? extends Function<?, Object>> supplier1 = () -> a -> a;
                return supplier1;
            };
        }
    }""");

However, each of the following succeed:

Launcher.parseClass("""
    public class Test {
        public static void test() {
            final Supplier<Object> supplier = () -> {
                final Supplier<Function<?, Object>> supplier1 = () -> a -> a;
                return supplier1;
            };
        }
    }""");

Launcher.parseClass("""
    public class Test {
        public static void test() {
            final Supplier<Object> supplier = () -> {
                final Supplier<? extends Supplier<?>> supplier1 = () -> () -> new Object();
                return supplier1;
            };
        }
    }""");

Launcher.parseClass("""
    public class Test {
        public static void test() {
            final Supplier<? extends Function<?, Object>> supplier = () -> a -> a;
        }
    }""");

In other words, it only seems to apply with the combination of the local definition being within a lambda, the extends being present, and the nested type being parameterized by more than one type (so that it is split on the comma when the outer one is being processed)
