What did you do?

Launched an App Engine Java 8 standard edition app. Some time after terminating, I noticed an error on my console:

!ENTRY org.eclipse.debug.core 4 2 2021-04-01 10:26:01.148

I have the same issue but with Cloud Tools for Eclipse version: 1.8.4 Google Cloud SDK version: 438.0.0 IDE: Spring Tool Suite 4 IDE: Version: 4.14.1.RELEASE IDE: Build Id: 202204250734 OS: macOS Version 13.4.1 (c) (22F770820d) 3 GHz 6-Core Intel Core i5 Java version: Java SE 8 [1.8.0_202]

Unrecognized option: --add-opens Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

@Ihernandezpi Unrecognized option: --add-opens means the --add-opens flag (which was added in Java 9+) was passed to Java 8 JVM. Try using recent Java versions.

might be related to https://github.com/GoogleCloudPlatform/appengine-plugins-core/issues/916 which was since fixed (https://github.com/GoogleCloudPlatform/appengine-plugins-core/pull/917) (maybe need to bump the lib version?)
