Hi,
Please be aware that we are making changes to rename the default installation directory name from glassfish4 -> glassfish5. All references to glassfish4 will be changed to glassfish5 which includes not just Java code but also all text files, scripts, test config files, l10n strings, build files etc. We will be taking care of developer tests as well.
If you have scripts, shell aliases, Hudson/Jenkins job configs etc. that use glassfish4, please be prepared to change over.
The changes are being reviewed in PR #21739 <
https://github.com/javaee/glassfish/pull/21739> and will be merged in the next day or two.
