I'm using JDBC SQL Server dependency in my project:
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>7.2.2.jre8</version>
</dependency>
As you can see I'm using version 7.2.2.jre8 and not 7.2.2.jre11.
I checked my java version with java -version and it says it's Java 1.8. I also checked Eclipse > Preferences > Java > Installed JREs and made sure I'm pointing to C:\Program Files\Java\jdk1.8.0_241. I also checked project's build path and Tomcat configuration and both point to this JDK. Maven's source and target tags are both set to 1.8.
Despite all of this, this exception is being thrown, which makes no sense to me, as I am using Java runtime 52 (Java 8) and the dependency I'm using is for java 8:
Caused by: java.lang.UnsupportedClassVersionError: com/microsoft/sqlserver/jdbc/SQLServerDriver has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
