We were running JanusGraph within a container that was running on Java 8, we didn't have any issues in running the graph. When we migrated our container to Java 11 due to security reasons, JanusGraph stopped working. Though we did not get any error related to Java version, we were stuck on this JanusGraphFactory.open(this.db_property_file) line forever. There were no errors nor any warnings. It just halts here. If there were any errors it would have helped us go in some direction. Pasting the property file and pom file below for reference.
graph = JanusGraphFactory.open(this.db_property_file); // Stuck on this line

- Tried upgrading the JanusGraph core version to 1.0.0rc2
- Checked if the property file is open somewhere so deadlock is ruled out
- Validated with Java 8 Image and it works fine
