JFE loads profile.ijs which in turn loads several other scripts. A profile error can be difficult to debug.
In jconsole you see the error but have no information on which script has the error.
In a gui JFE there probably isn't even an ijx window to show the error.
Debugging profile errors can be difficult, but the following steps may help.
1. Start jconsole with -jprofile. This will give a bare bones ijx window in which to track down the error.
2. BINPATH_z_ is the full path to the profile.ijs to load. First make sure that it exists.
BINPATH C:\j803\bin #1!:1<BINPATH,'\profile.ijs' 18633. Define
DISPLAYLOAD_j_=: 1 0!:0<BINPATH,'\profile.ijs' ...4. Use a texteditor to examine the script with the error and fix it.
