RE: Jpcsp problem :c
sorry for double post but if you want more information look at this:

@echo off
rem CD to the path of the command line, this is required when running as an administrator
cd /D "%~dp0"

set PATH=%PATH%;lib\;lib\windows-x86\

if NOT EXIST "%SystemRoot%\SysWOW64" goto JAVA32
set key=HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment
goto JAVA

:JAVA32
set key=HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment

:JAVA
set JAVA_CMD=%ProgramFiles%\Java\jre7\bin\java.exe
if not exist "%JAVA_CMD%" set JAVA_CMD=java.exe

rem Checking if the "reg" command is available
reg /? >NUL 2>NUL
if ERRORLEVEL 1 goto RUN

set JAVA_VERSION=
set JAVA_HOME=
for /f "tokens=3* skip=2" %%a in ('reg query "%key%" /v CurrentVersion') do set JAVA_VERSION=%%a
for /f "tokens=2* skip=2" %%a in ('reg query "%key%\%JAVA_VERSION%" /v JavaHome') do set JAVA_HOME=%%b

set JAVA_CMD=%JAVA_HOME%\bin\java.exe
if not exist "%JAVA_CMD%" goto JAVAMISSING

:RUN

rem Use -Xmx768m for Windows XP, -Xmx1024m for all other Windows versions
set MAX_MEM_SIZE=1024m
ver | findstr "5\.1\." > nul
if %ERRORLEVEL% EQU 0 set MAX_MEM_SIZE=768m

echo Running Jpcsp 32bit...
"%JAVA_CMD%" -Xmx512m -Xss2m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=64m -Djava.library.path=lib/windows-x86 -jar bin/jpcsp.jar %*
if ERRORLEVEL 1 goto PAUSE
goto END

:JAVAMISSING
echo The required version of Java has not been installed or isn't recognized.

RE: Jpcsp problem :c
I don't get why you post JPCSP start batch; it is the code needed to JPCSP start.

The problem with your machine is that log4j have some kind of bug or something. How long since you don't update your Java? If it so long then delete it all, and the make a clean installation of latest Java.

If on the other side, you recently update java, then try a downgrade instead.

RE: Jpcsp problem :c
Java latest update does not break anything and all versions of Jpcsp work fine.
