JRuby installer (install4j) sometimes detects an incorrect user.home under
VMWare with network drives mounted
-------------------------------------------------------------------------------------------------------------
Key: JRUBY-5777
URL: http://jira.codehaus.org/browse/JRUBY-5777
Project: JRuby
Issue Type: Bug
Components: Application Error
Affects Versions: JRuby 1.6.1
Environment: Host OS is OSX 10.6.6 running Windows 7 x64 SP1 under
VMWare Fusion 3.0.2
VMWare Fusion is mapping Documents, Desktop and one directory containing a
development tree
JRE 1.60_25 32-bit
installer was jre-6u25-windows-i586-iftw.exe
Reporter: Chuck Remes
After installation, the gem env contained a network path "\\vmware-host\Shared
Folders" which prevented me from installing any gems.

Gem installation resulted in an ENOENT error complaining about the
aforementioned network path.

After a few hours of searching, I discovered that the
c:\jruby-1.6.1\.install4j\installation.log file contained a line showing that
"user.home" was set to the network path instead of the *real* home of
c:\Users\cremes. I created a new system environment variable HOME and set it to
c:\Users\cremes and reinstalled. The installer log picked up the correct %HOME%
value and the gem env was also corrected.
After that minor change, gem installation worked correctly.
It is my assumption that the installer logic used for detecting the HOME
directory has a flaw. I don't have easily reproducible steps though. It doesn't
appear to affect all VMWare Fusion environments (on IRC I led another user
through the steps under VMWare and his installation worked correctly even
though he did *not* have a %HOME% variable set).
