[jira] [Resolved] (DAEMON-445) Changes of DAEMON-441 cause trouble with empty env vars

["Mark Thomas (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DAEMON-445?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mark Thomas resolved DAEMON-445.
--------------------------------
    Resolution: Cannot Reproduce

I have tried the registry approach to create an empty environment variable on all currently supported versions of Windows without success. I am therefore resolving this issue as cannot reproduce.

I have no objections to this issue being re-opened if steps are provided to recreate it on a fully patched installation of any currently supported (by Microsoft) Windows operating system.

> The changes done via DAEMON-441, namely [https://github.com/apache/commons-daemon/commit/97b31058ecf5e4dc202188d8e8917f6caa90dcfc#diff-e7f9bbe0d9947378640c1e1c91d8dc72c93e6d1034218458158a1cc43f2f3b9fR278] lead to a failing service installation in case the environment variable exists but has no value. 
> In my use case the supported environment variables are explicitly set empty if defaults shall be used. This is done to avoid interference with environment variables which may be set by the caling process. 
> In such a case example output is:
> {noformat}
