null file is created in bin directory when starting standalone.bat ------------------------------------------------------------------ Key: WFCORE-4335 URL: https://issues.jboss.org/browse/WFCORE-4335 Project: WildFly Core Issue Type: Bug Components: Scripts Affects Versions: 8.0.0.Beta3 Reporter: Marek Kopecký Assignee: Teresa Miyar Priority: Critical When starting standalone.bat on Windows, a file named "null" is created in the bin directory. Looking at the standalone.bat file, I find this new line which was added: rem Remove the gc.log file from the -version check del /F /Q "%JBOSS_LOG_DIR%\gc.log" > null 2>&1 But, this is a typo. What it's trying to do is suppress the output of the del command. In unix, you'd redirect it to /dev/null. In Windows, you're supposed to redirect it to nul (with one L), as in this example line from slightly earlier in the standalone.bat file: move /y "%JBOSS_LOG_DIR%\gc.log" "%JBOSS_LOG_DIR%\backupgc.log" > nul 2>&1
