Recently, I was upgrading my Java version in one of the repositories and I came across this issue. I was using maven for building this project. In my pom.xml file, I simply declared target as Java version 17 and I came across this error.

This is what it looks like in my pom.xml file.

1<properties>
2    <maven.compiler.source>17</maven.compiler.source>
3    <maven.compiler.target>17</maven.compiler.target>
4</properties>

Problem

After changing this to 17, when I run my test cases using mvn clean test, I get below error.
