This seems to have been the problem. I out-commented the following two lines: "%JAVA%" -server -version 2>&1 | findstr /I hotspot > nul | if not errorlevel == 1 (set JAVA_OPTS=%JAVA_OPTS% -server) and replaced them with the following line set JAVA_OPTS=%JAVA_OPTS% -server Now it works properly. Thanks a lot :) But I´m still slightly confused how it doesn´t seem to find the "findstr.exe". It is placed inside the "WINNT\System32\" directory, which is included in the PATH environmental variable.
