---------------------------------------
Summary: NPE in Call hierarchy
Key: NETBEANS-5471
URL: https://issues.apache.org/jira/browse/NETBEANS-5471
Project: NetBeans
Issue Type: Bug
Affects Versions: 12.3
Reporter: Hynek Mlnarik
I keep getting occasional NPEs when looking through Call hierarchy in Java
project.
Steps to reproduce:
# Clone [https://github.com/keycloak/keycloak/] (a big project - may be a
factor)
# Pick a method, use Call hierarchy.
# Walk the call hierarchy by expanding the nodes
# Observe random NPEs
