Sakai builds and runs fine (OOTB, with only default configuration), but during initial startup a DB exception is thrown, apparently indicating that a table doesn't yet exist when it needs to:
java.sql.SQLException: Table not found: SAKAI_SESSION in statement [select EVENT
_ID,EVENT_DATE,EVENT,REF,SAKAI_EVENT.SESSION_ID,EVENT_CODE,SESSION_SERVER from S
AKAI_EVENT,SAKAI_SESSION where (SAKAI_EVENT.SESSION_ID = SAKAI_SESSION.SESSION_I
D) and (EVENT_ID > ?)]
at org.hsqldb.jdbc.jdbcUtil.throwError(Unknown Source) ...<stack trace follows>
There doesn't appear to be any consequences for the software when it comes up, but this may indicate an issue that could be corrected.
