jmeter.bat don't use the JM_LAUNCH to test java version, so java versions could be different

**vdaburon** ([Bug 59052](https://bz.apache.org/bugzilla//show_bug.cgi?id=59052&redirect=false)):
Hi,

You could set the JM_LAUNCH but this information is not used to detected the java version, so JM_LAUNCH and 'java' could have differents versions

rem JM_LAUNCH - java.exe (default) or javaw.exe

set JM_LAUNCH=d:\java\jdk1.7

but the java -version 2^>^&1 use the version in the PATH not the JM_LAUNCH

...
for /f "tokens=3" %%g in ('java -version 2^>^&1 ^| findstr /i "version"') do (
rem @echo Debug Output: %%g
set JAVAVER=%%g
)

Regards.
