Currently the Java Debugger and Test Runner have the duplicated logic to check JDK installation directory. Could the vscode-java return the resolved RequirementsData value as the return value of activate function? By this way, other extensions can get the resolved java_home info directly.

   const extension = vscode.extensions.getExtension("redhat.java");
   const extensionApi = await extension.activate();
   return extensionApi.requirementsData;
