Contradicting candidate preferences

[Geosearchef]

According to the comment at

ice4j/src/main/java/org/ice4j/ice/Candidate.java

Line 558 in 28a23e1

//prefer IPv6 to IPv4

, IPv6 is preferred to IPv4, this is indicated using preference values 30,40 > 10.

But the comment says, that link local is preferred to global. This is reflected by the value for link local, 30, being larger than the value for global, 40.

Shouldn't these two values be the other way round?

what version of JAVA are you running? Java SE 17 and beyond fixes the IPv6 issues. Java SE 7 or prior version failed IPv6 in many situations.
