Slow execution of standalone.bat from JBoss EAP 6.1.0

Issue

Following part of standalone.bat takes 40 seconds to execute:

: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

Would it be possible to optimize above?
