There is an issue in the online installer code which does not use the correct method for the ping if the short name of the jxpinstall.exe is used. Currently, it only uses the right method if the full jxpi installer name is used, such as jxpiinstall-6u10-fcs-bin-b33-windows-i586-26_sep_2008.exe. At the mean time, as the workaround, change the jxpiinstall.exe to the full name which is in the same promoted build output location.
Needs to modify the code to use the correct method for ping when short name jxpiinstall.exe is used. The fix is in jinstall.cpp.
