While when I was debugging this test with jdb, and set a breakpoint at L351, I hit a strange behavior. If I print run at once, the test will fail. But if I wait one minute and then print run, this test will pass.
For example, if I type print db.get(key) several times quickly at once when the code stopping at L351. You can see that the value is not updated at once:
main[1] print db.get(key)
db.get(key) = instance of byte[1073741824] (id=1042)
main[1] print db.get(key)
db.get(key) = instance of byte[1073741824] (id=1043)
main[1] print db.get(key)
db.get(key) = instance of byte[1073741824] (id=1044)
main[1] print db.get(key)
db.get(key) = instance of byte[1073741824] (id=1045)
main[1] print db.get(key)
Exception in expression: org.rocksdb.RocksDBException
db.get(key) = null
Any suggestion about this case? Is it related to RocksDB cache or anything else.? Need any idea.
Thanks.
