That's because the setting java.configuration.runtimes in JDTLS is globally effective. Though its scope is machine-overridable, it won't take effect if you set different values for different workspace folders.

java.configuration.runtimes defines mappings of language levels and JDK distributions, which is globally effective. We are lacking the ability to set different runtimes even for different workspace. E.g. Below case is impossible for the moment:

• Workspace A: uses Redhat's OpenJDK 17, JAVASE-1.8
• Workspace B: uses Microsoft's OpenJDK 11, JAVASE-1.8

@CsCherrYY It's just the case we discussed before. One option is to re-define this setting as a collection of pairs of JDK distro and language level. E.g. make "java.configuration.runtimes" machine-scoped, and add a new setting like java.default.runtime referencing one of above runtimes using a unique name.

"java.configuration.runtimes": [
    {
        "name": "Java 8 with JDK 17",
        "level": "JavaSE-1.8",
        "path": "C:\\Program Files\\Eclipse Adoptium\\jdk-17.0.1.12-hotspot"
    },
    {
        "name": "my-JDK17",
        "level": "JavaSE-17",
        "path": "C:\\Program Files\\Eclipse Adoptium\\jdk-17.0.1.12-hotspot",
    }
],

"java.default.runtime": "my-JDK17"
