We are using JDBC 11.2 and it is compatible with JRE 1.8, as per below KB article. But we keep getting error as "UnsupportedClassVersionError".
https://knowledge.broadcom.com/external/article/216679/error-processing-request-for-de-client.html
java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=com/microsoft/sqlserver/jdbc/SQLServerDriver
Release: All Supported Versions
Component: CA Workload Automation System Agent
When you download the drivers from MicroSoft, you have 4 jar files each one is for particular version of java. You need to use only copy one of them "mssql-jdbc-11.2.0.jre8.jar".
Note # This issue occurs when you post all the file.
