+All configured Java versions are added to the PATH. The last one added to the PATH (i.e., the last JDK set up by this action) will be used as the default and available globally. Other Java versions can be accessed through environment variables such as 'JAVA_HOME_{{ MAJOR_VERSION }}_{{ ARCHITECTURE }}'. To use a specific Java version, set the JAVA_HOME environment variable accordingly and prepend its bin directory to the PATH to ensure it takes priority during execution.

 If the file contains multiple versions, only the first one will be recognized.

+***NOTE***:
+For the tool-version file, ensure that you use standard semantic versioning (semver) formats, as non-standard formats (such as jetbrains-21b212.1) may not be parsed correctly. Additionally, for complex version strings containing multiple version-like segments (for example, java semeru-openj9-11.0.15+10_openj9-0.32.0), the extraction logic may incorrectly capture the last segment (0.32.0) instead of the main version (11.0.15+10).
