             Summary: solr.cmd on Windows requires modify permissions in the current directory
                 Key: SOLR-9760
                 URL: https://issues.apache.org/jira/browse/SOLR-9760
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Server
    Affects Versions: 6.3
         Environment: Windows
            Reporter: Alex Crome


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,
