[Error Installing JasperReports Server Community Edition using js-install-ce.bat on Windows 8.1 Pro]

with windows 6.1.0 installer I was getting the below warning and the same error as above in installation.log.
 I removed the JAVA_TOOL_OPTIONS and _JAVA_OPTIONS from env variables. Jasperreport server got installed successfully after that.
