Java JDK (or JRE) 8 or more recent
Ensure Java path is set in either:
xml.java.home in VSCode preferences
java.home in VSCode preferences
Environment variable JAVA_HOME or JDK_HOME
Note: The path should end at the parent folder that contains the bin folder. Example Path: /usr/lib/jvm/java-1.8.0 if bin exists at /usr/lib/jvm/java-1.8.0/bin.
Note: If the path is not set, the extension will attempt to find the path to the JDK or JRE.
