Underscore in table name gives "Table not found" log

When I deploy my application in WildFly, I get a bunch of log statements from hibernate for tables with underscore in the name:

2016-05-03 11:39:25,344 INFO [org.hibernate.tool.schema.extract.internal.InformationExtractorJdbcDatabaseMetaDataImpl] (ServerService Thread Pool – 61) HHH000262: Table not found: AAA_BBB

I've investigated a bit and found that it is due to the usage of sp_tables. This (which is what Hibernate uses) does not work:

exec sp_tables N'AAA_BBB',N'',N'MyDb',N'''''''TABLE'''',''''VIEW''''''', @fUsePattern = 1

This however, works:

exec sp_tables N'AAA_BBB',N'',N'MyDB',N'''''''TABLE'''',''''VIEW''''''', @fUsePattern = 0
