https://hibernate.atlassian.net/browse/HHH-13671?atlOrigin=eyJpIjoiN2RjMT... ) SequenceInformationExtractorLegacyImpl fails on Oracle 12.1 for sequence with low min_value ( https://hibernate.atlassian.net/browse/HHH-13671?atlOrigin=eyJpIjoiN2RjMT... ) Change By: Björn Peemöller ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Hi, I encountered the following problem with Hibernate 5.4.6 in the following situation: * Oracle 12.1 database * Sequence with MIN_VALUE=-1E27, MAX_VALUE=-1 If in this situation I start up my Spring Boot application, the database sequences get analyzed by the {{SequenceInformationExtractorLegacyImpl}} and I get the following stack trace: {code:java}2019-10-17 13:46:32.545 ERROR 21352 ---

here is that the minimal value of the sequence is requested as a {{java.lang.Long}} in {{SequenceInformationExtractorLegacyImpl.resultSetMinValue(SequenceInformationExtractorLegacyImpl.java:134)}} but represented as a {{NUMBER(38)}} in the database, and for the value {{-1E27}} an overflow occurs, since it cannot be represented as a {{java.lang.Long}}.
