Spring with HSQLDB latest 2.4.0 version not working

Question

I am trying to create simple Java 1.7 project for Spring with HSQL DB. I downloaded latest version of HSQL DB and created a simple file based DB.

In java project I am using latest version of Spring, HSQL and related jar. But while running program I am getting error

Exception in thread "main" java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/hsqldb/jdbcDriver, offset=6

My file is

        <!-- Spring framework -->
        <!-- https://mvnrepository.com/artifact/org.springframework/spring-context -->
        <dependency>

<version>2.4.0</version>

What should be change in jars ?

Answer 1

HSQLDB 2.4.0 has been compiled with JDK 8 and cannot be used with JDK 7 or earlier.

You need to specify version 2.3.5 for a version that has been compiled with JDK 6. This version lacks the new JDBC features introduced in Java 8 but is compatible with version 2.4.0 in other respects.
