Hello @Dmitry Bocharov ,

The problem is exactly in this class ('SequenceInformationExtractorOracleDatabaseImpl') . There is no implementation for resultSetMinValue.

When you use the default value in Oracle 12 which is -999999999999999999999999999 for negative sequence, the exception is thrown, because it uses the parent’s method, which returns “Long”. Obviously this number( -999999999999999999999999999 ) can not be handled in long ( it’s too big ) and exception is thrown.
