AI Summary: Update the Eclipse GlassFish upgrade guide to reflect current practices. This involves removing obsolete information about GUI-based upgrade tools and replacing references to the `asupgrade` command with the modern `asadmin start-domain --upgrade` command. The guide should be clarified to explain that upgrading is done in-place and instructions for handling remote cluster upgrades and potentially using backup/restore commands should be reviewed and updated.

AI Summary: Automate the updating of component versions in the Eclipse GlassFish installation guide. This involves redefining Maven properties without periods in the parent docs pom.xml and replacing version references in Asciidoc files with the new properties. Additional components may need to be added to the guide.

AI Summary: The task is to fix a bug in the Eclipse GlassFish EmbeddedVirtualServerHostNameTest. The test currently fails to properly dispose of the GlassFish runtime, resulting in leftover temporary directories. The solution involves modifying the test to ensure the `glassfish.dispose()` method is called in the cleanup phase, likely by storing the GlassFish runtime in an instance variable instead of a local variable.
