Description of problem: Standalone.bat performs poorly when anti-virus software is running and there are many -D parameters set

Here is my times with anti-virus:
 START SCRIPT TIME  : 15:56:49.08
 DIRLOOP START TIME : 15:56:50.09 (+1s 01)
 DIRLOOP END TIME   : 15:57:21.88 (+31s 79)

 Jboss start time in 1 665 ms 

Times without AV (on a differnt machine - this explain JBoss start-up time difference):
 START SCRIPT TIME  : 16:21:47.51
 DIRLOOP START TIME : 16:21:47.87 (+0s 36)
 DIRLOOP END TIME   : 16:21:49.31 (+1s 44)

 Jboss start time in 11 219 ms

How to reproduce:

Run standalone.bat with many parameters - for example 
by adding the following to the standalone.conf.bat file

set JAVA_OPTS=%JAVA_OPTS% -Dkey01=value01 -Dkey02=value02 -Dkey03=value03 -Dkey04=value04 -Dkey05=value05 -Dkey06=value06 -Dkey07=value07 -Dkey08=value08 -Dkey09=value09 -Dkey10=value10
set JAVA_OPTS=%JAVA_OPTS% -Dkey11=value11 -Dkey12=value12 -Dkey13=value13 -Dkey14=value14 -Dkey15=value15 -Dkey16=value16 -Dkey17=value17 -Dkey18=value18 -Dkey19=value19 -Dkey20=value20
set JAVA_OPTS=%JAVA_OPTS% -Dkey21=value21 -Dkey22=value22 -Dkey23=value23 -Dkey24=value24 -Dkey25=value25 -Dkey26=value26 -Dkey27=value27 -Dkey28=value28 -Dkey29=value29 -Dkey30=value30

Running on a machine with no anti-virus standalone.bat takes ~ 1s to process
Running on a machine with ant-virus software on it it can take about 30 s to process the script.

Analysis has shown that the problem is due to the following loop (and specifically echo with findstr) creating many temporary files. These temp files then get scanned by the virus checker thus slowing down execution.

rem Setup JBoss specific properties

rem Setup directories, note directories with spaces do not work
set "CONSOLIDATED_OPTS=%JAVA_OPTS% %SERVER_OPTS%"
:DIRLOOP
echo(%CONSOLIDATED_OPTS% | findstr /r /c:"^-Djboss.server.base.dir" > nul && (
  for /f "tokens=1,2* delims==" %%a IN ("%CONSOLIDATED_OPTS%") DO (
    for /f %%i IN ("%%b") DO set "JBOSS_BASE_DIR=%%~fi"
  )
)
echo(%CONSOLIDATED_OPTS% | findstr /r /c:"^-Djboss.server.config.dir" > nul && (
  for /f "tokens=1,2* delims==" %%a IN ("%CONSOLIDATED_OPTS%") DO (
    for /f %%i IN ("%%b") DO set "JBOSS_CONFIG_DIR=%%~fi"
  )
)
echo(%CONSOLIDATED_OPTS% | findstr /r /c:"^-Djboss.server.log.dir" > nul && (
  for /f "tokens=1,2* delims==" %%a IN ("%CONSOLIDATED_OPTS%") DO (
    for /f %%i IN ("%%b") DO set "JBOSS_LOG_DIR=%%~fi"
  )
)

for /f "tokens=1* delims= " %%i IN ("%CONSOLIDATED_OPTS%") DO (
  if %%i == "" (
    goto ENDDIRLOOP
  ) else (
    set CONSOLIDATED_OPTS=%%j
    GOTO DIRLOOP
  )
)

:ENDDIRLOOP



It is recommended this loop be re-rewritten so temp files aren't created as running withou anti-virus is not a good idea.
