Mark Thomas updated DAEMON-394:
-------------------------------
Fix Version/s: 1.2.0
> Monitor application will update multi-string values in Windows registry with
> blank lines
> ----------------------------------------------------------------------------------------
>
> Key: DAEMON-394
> URL: https://issues.apache.org/jira/browse/DAEMON-394
> Project: Commons Daemon
> Issue Type: Bug
> Components: Procrun
> Affects Versions: 1.1.0
> Environment: OS: Windows 7 Pro, Service Pack 1
> Reporter: Brandon
> Priority: Major
> Labels: windows
> Fix For: 1.2.0
>
>
> The Procrun Monitor application does not prevent a user from accidentally
> inserting blank lines into the Java Options or Java 9 Options text areas. If
> a blank line is introduced into either text area and the changes are applied
> (by hitting the Apply or OK button), the changes are committed to the
> associating multi-string value in the Windows registry.
> If a user were to relaunch the Monitor application and view the Java or Java
> 9 Options again, they would see that the content has been truncated.
> Individual options above the blank line remain; any below are not present. If
> the Windows Registry editor were used to view the associating multi-string
> value, the user would see all of the content including the blank line.
> Changing the options again from within the Monitor application will succeed
> but when the options are committed to the registry multi-string value, any
> options that existed below the blank line will be removed.
> Note that the Windows registry editor will display an error dialog if a user
> attempts to save a multi-string value with an empty line present. The message
> is: "Data of type REG_MULTI_SZ cannot contain empty strings. Registry Editor
> will remove all empty strings found."
> Steps to Reproduce:
> # Download latest Commons Daemon distribution for windows (1.1.0).
> # Run prunsrv.exe to install a test service (TestService).
> # Run prunmgr.exe //ES/TestService to start the monitor application to edit
> the same TestService.
> # Switch to the Java tab and edit either the Java Options or Java 9 Options.
> Insert a bunch of options and then Insert a blank line somewhere in-between
> those options. Click OK
> # Run prunmgr again. Look at the Java Options or Java 9 Options where the
> blank line was inserted. Notice that all options below the blank line are not
> visible.
> # Open up the registry editor and navigate to the multi-string value
> associated with the Java Options text area:
> HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun
> 2.0\TestService\Parameters\Java
> # Notice that all content is present (including the blank line) in the
> registry value.
