Hello.
I'm trying to upgrade H2 used in our tests from 1.3.154 to 1.4.190
After test finish I can see such exceptions in the log
org.h2.jdbc.JdbcSQLException: Timeout trying to lock table "SYS" [50200-160]

What can be cause of that? How to identify what cause is?
I checked intermediates versions. This problem is reproduced with H2
1.3.160+
1.3.159 works fine, any version started with 1.3.160 have such issue.
