对于那些具有强迫症的工程师来说，软件汉化固然好用，但是汉化不完整却极为头疼，本方法针对iReport汉化不完整的情况，强制使用英文版，方法如下：
在 iReport 安装路径下的 etc/ireport.conf 里增加红色部分启动参数，即可变为英文版。
# ${HOME} will be replaced by user home directory according to platform
default_userdir="${HOME}/.${APPNAME}/4.0.1"
default_mac_userdir="${HOME}/Library/Application Support/${APPNAME}/4.0.1"
# options used by the launcher by default, can be overridden by explicit
# command line switches
default_options="-J-Duser.language=en -J-Duser.region=US -J-Dfile.encoding=UTF-8 --branding ireport -J-Xms128m -J-Xmx512m -J-Dorg.netbeans.ProxyClassLoader.level=1000 -J-XX:MaxPermSize=256m"
# for development purposes you may wish to append: -J-Dnetbeans.logger.console=true -J-ea
# default location of JDK/JRE, can be overridden by using --jdkhome <dir> switch
#jdkhome="/path/to/jdk"
# clusters' paths separated by path.separator (semicolon on Windows, colon on Unices)
