[jboss-jira] [JBoss JIRA] (WFCORE-3867) Space char always last char of read system property on Windows

[R Searls (JIRA)]

R Searls commented on WFCORE-3867:
----------------------------------

This is not the script providing a text string with a space char at the end.  I have confirmed that in the script in which I had this issue.  I believe this is a "doc2unix" end of line issue.


{code:java}
In DOS/Windows text files a line break, also known as newline, is a combination of two characters: a
       Carriage Return (CR) followed by a Line Feed (LF). In Unix text files a line break is a single character:
       the Line Feed (LF). In Mac text files, prior to Mac OS X, a line break was single Carriage Return (CR)
       character. Nowadays Mac OS uses Unix style (LF) line breaks.
{code}

I confirmed (when running on Windows) that every system var that was being read in had this space char at the end.   Windows just happens to allow paths with spaces in them.  An env var of  JBOSS_HOME="C:\user\me\wfly-13" and server appending "module" to it generated a path "C:\user\me\wfly-13  \module" which is valid on windows.  Only when the env path itself,  "C:\user\me\wfly-13 ",  was being process does the call to Path.toPath().*toRealPath()* fail with an invalid path exception.

> On Windows each system property read has a space char as the last char of string.
> This causes failures when the property represents a directory name.  Calling 
> tmp.toPath().toRealPath() in this situation.
> ServerEnvironment line, 434  Path resolved = tmp.toPath().toRealPath();
