 You didn't speak with me, but I can't abstain from pointing out that:

 The PATH environment variable is supposed to be in Unix format under
Cygwin and so the above will _not_ work because the colon, in its second
position, will be interpreted as a separator, i.e. you'd be setting up a
PATH with 2 directories, "c:" and "/Program Files/...".

 The correct command morally equivalent to the one above would be

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

but I'd also append to the PATH rather than replacing it just in case java
itself expects to find some DLLs in the standard PATH (which is unlikely
but not impossible), so my recommended command would be:

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

 Hope this helps,
