When connecting to hsqldb from squirrel, I get the following error in studio console:
org.hsqldb.HsqlException: Client driver version greater than '2.3.4.0' is required. HSQLDB server version is 'version'
at org.hsqldb.error.Error.error(Unknown Source)
at org.hsqldb.server.ServerConnection.init(Unknown Source)
at org.hsqldb.server.ServerConnection.run(Unknown Source)
at java.lang.Thread.run(Thread.java:745)
although I’m using the latest version of the driver.
