We haven't tried it on Vista. Obviously it's this line in bin/run.bat: | ... | rem Add -server to the JVM options, if supported | "%JAVA%" -version 2>&1 | findstr /I hotspot > nul | if not errorlevel == 1 (set JAVA_OPTS=%JAVA_OPTS% -server) | ... | Just change it to: | set JAVA_OPTS=%JAVA_OPTS% -server | and try again.
