When launching node.bat on my test rig :
juin 05, 2018 1:20:14 PM snowblossom.db.rocksdb.JRocksDB
INFOS: Loadng RocksDB with path snowdb
Exception in thread "main" java.lang.ExceptionInInitializerError
W10, java updated, rig rebooted
Try setting in your node.conf:
db_type=lobstack
This is a known issue. We had more notes about it, but might have been lost in a wiki fire.
