[lmi] Path for "java"

[Greg Chicares]

[I sent email containing this:

> [I've mangled these commands so that they don't
> get clobbered by "security" software--where I've written
> lowercase X Y and Z, substitute lowercase E X and E]:
>   dir /s java.xyz
> If that doesn't work, try:
>   where java.xyz

to a corporate address today, but their "security" software
mangled both commands beyond recognition, and I had to read
them over the telephone. If I didn't speak with you on the
telephone today, you can ignore this message.]

We use "java" only for Relax NG, and for that reason I'd like
to figure out how to find 'java.exe' from Cygwin--without
adding the whole 1393-character $PATH set by corporate IT.
Based on the result of this "dir" command on the target
machine (from which I've removed five directories specific
to a middleware company that doesn't "own" the language):

---------8<--------8<--------8<--------8<--------8<--------8<--------8<-------
C:\>dir /s java.exe
 Volume in drive C is [REDACTED]
 Volume Serial Number is [REDACTED]

 Directory of C:\Program Files (x86)\Common Files\Oracle\Java\javapath

               1 File(s)        192,376 bytes

Files\Oracle\Java\javapath_target_1634306390

2019-04-29  09:53 AM           192,376 java.exe
               1 File(s)        192,376 bytes

 Directory of C:\Program Files (x86)\Java\jre1.8.0_211\bin

2019-04-29  09:53 AM           192,376 java.exe
               1 File(s)        192,376 bytes
--------->8-------->8-------->8-------->8-------->8-------->8-------->8-------

...I speculate that this command:

PATH="C:/Program\ Files\ \(x86\)/Common\ Files/Oracle/Java/javapath" java 
-version

will do the expected thing in a cygwin terminal, so I've
added that string to the $PATH in commit 87c94d43. But it's
hard to guess whether I cygwin-ified that correctly, so
please read this message in the mailing list's html archives,
and copy and paste that command and let me know if it fails.
