StackOverflowError for leafref

I want to generate JAVA classes from ietf-ospf, I hit StackOverflowError at the following definition, and the generation failed.

list neighbor {
description
"List of neighbors.";
leaf neighbor-id {
type leafref

description "Neighbor.";
}
}

If I replace path "../../neighbor/neighbor-id" with concrete path "/rt:routing-state/rt:routing-instance/"
+ "rt:routing-protocols/rt:routing-protocol/"
+ "ospf:ospf/ospf:instance/ospf:neighbor/ospf:neighbor-id";", the error is solved.

How can we solve the StackOverflowError without modifying ietf-ospf file? Could we fix it in yang-tools? Thank you!

ietf-ospf.yang file is attached. Error message is:
