Sorry, fell down a rabbit hole yesterday. I've attached some .e files for you to try out. Save the attached files - it's fine just to dump them in your Downloads directory.
For each of the saved files, go to the SlickEdit command line and "load" the file. So for c.e, you'd do something like "load /some/path/c.e".
As you type, a debug window may come up. I tried to make the debugging so it's only chatty when something suspicious is happening, but it will probably come up before you have a javadoc failure. Just iconify the debug window and continue. When you run into the problem, bring that debug window back up, and hit Ctrl-C when it has focus - that will copy all of the debug messages to the clipboard. And then paste those messages into a reply.
Afterwards, if you want to kill the debug logging, you can load the versions of the attached .e that we shipped with, ie: load SLICKEDIT_INSTALL_PATH/macros/c.e
