I have been programming a java project using JDK14 and VSCode. Recently JDK15 is available, and I switched to the JDK. As for configuration, I pointed the VScode java.home and system JAVA_HOME to the new JDK folder.

When I clear the VSCode cache and restart the IDE, I started receiving this error

{
"resource": "/E:/dev/java/challenges/",
"owner": "_generated_diagnostic_collection_name_#3",
"code": "963",
"severity": 8,
"message": "Unbound classpath container: 'JRE System Library [JavaSE-15]' in project 'challenges'",
"source": "Java",
"startLineNumber": 1,
"startColumn": 1,
"endLineNumber": 1,
"endColumn": 1
}

I have seen similar questions/answers, but none of them was directed to VSCode.

According to VsCode-Java in Twitter, JDK15 support won't be released until the end of September, and here is a github issue that's related to Java 15 not support.
