      In DB2, unlike other Databases, it will throw a System Exception by denying the query if you try to perform a SELECT statement on an object who has a field who exceeds the DB supported length.

      This affects AssetTagLocalService.addTag(...) because we validate the name AFTER we check for duplicate tags (performs a fetch). We should validate the name first so we don't execute a DB query on a bad name, to improve both performance and stability.

      Steps to Reproduce

      1. Start up Portal with DB2 (or just run ci:test:backend and check axis results after)
      2. Run com.liferay.asset.service.test.AssetTagLocalServiceTest.testIncrementAssetCountWithAssetTagNameGreaterThan75

      Expected Result
      Integration test passes

      Actual Result
      Integration test fails

      Tested on Tomcat 9.0.17 + MySQL 5.7
