> Currently starting solr fails if the user does not have permission to write
> to the current directory. This is caused by the resolve_java_vendor function
> writing a temporary file to the current directory (javares).
> {code}
> :resolve_java_vendor
> set "JAVA_VENDOR=Oracle"
> "%JAVA%" -version 2>&1 | findstr /i "IBM J9" > javares
> set /p JAVA_VENDOR_OUT=<javares
> del javares
> if NOT "%JAVA_VENDOR_OUT%" == "" (
> set "JAVA_VENDOR=IBM J9"
> )
> {code}
> Rather than writing this temporary file to disk, The exit code of findstr can
> be used to determine if there is a match. (0 == match, 1 == no match, 2 ==
> syntax error)
> {code}
> :resolve_java_vendor
> "%JAVA%" -version 2>&1 | findstr /i "IBM J9" > nul
> if %ERRORLEVEL% == 1 set "JAVA_VENDOR=Oracle" else set "JAVA_VENDOR=IBM J9"
> {code}
> By not writing this temp file, you can reduce the permissions solr needs. As
> a work around until this is fixed, you can start solr in a directory that has
> the required permissions,
