-----------------------------------------
Resolution: Fixed
> cygpath call in "start" to convert CLASSPATH should first verify it's set
> -------------------------------------------------------------------------
>
> Key: KARAF-3964
> URL: https://issues.apache.org/jira/browse/KARAF-3964
> Project: Karaf
> Issue Type: Bug
> Components: karaf-core
> Environment: Windows 7, Cygwin
> Reporter: David M. Karr
> Assignee: Jean-Baptiste Onofré
> Priority: Trivial
> Fix For: 4.0.2, 3.0.6
>
>
> Several of the Karaf scripts have "if $cygwin" blocks that convert some
> variables to Windows form. If the variable referenced is not set, cygpath
> will fail with "cygpath: can't convert empty path". The impact is debatable,
> as the variable after the command will be unset, same as before it, but the
> error message can be confusing for users.
> Most of these cases are likely dealt with, but one that is not is in the
> "start" script, for the "CLASSPATH" variable. I don't set a global CLASSPATH
> value, and I believe it's generally a bad idea to set one.
> The most reasonable fix is to simply not run cygpath if CLASSPATH is not set
> or is empty. Therefore, change this:
> CLASSPATH=`cygpath --path --windows "$CLASSPATH"`
> to:
> if [ ! -z "$CLASSPATH" ]; then
> CLASSPATH=`cygpath --path --windows "$CLASSPATH"`
> fi
