Starting up the Java extension I get the following error:

[2020-06-09 10:13:00.576] [exthost] [error] Activating extension redhat.java failed due to an error:

Same as #1449, but different stack trace.

Checking my env, JAVA_HOME is not set

Comienza reproduciendo la activación de la extensión de Java en la versión indicada de VS Code Insiders con JAVA_HOME sin establecer y, a continuación, inspecciona la llamada a path.join que aparece en dist/extension.js. Compara el comportamiento y el stack trace con el issue #1449; se considera terminado cuando la extensión se activa sin el error notificado de argumento de ruta no válido.
