1. Start Emacs with -Q flag.
2. (setq debug-on-error t)
3. Open a .java file
4. M-x flymake-mode
5. Move point
Produces this debugger output:

In flymake-proc.el:
(defun flymake-proc--delete-temp-directory (dir-name)
"Attempt to delete temp dir created by
`flymake-proc-create-temp-with-folder-structure', do not fail on error."
(let* ((temp-dir temporary-file-directory)
(suffix (substring dir-name (1+ (length (directory-file-name
temp-dir))))))
(while (> (length suffix) 0)
(setq suffix (directory-file-name suffix))
;;+(flymake-log 0 "suffix=%s" suffix)
(flymake-proc--safe-delete-directory
(file-truename (expand-file-name suffix temp-dir)))
(setq suffix (file-name-directory suffix)))))
Line 901 should be
(let* ((temp-dir (file-truename temporary-file-directory))
This is because the default value of variable temporary-file-directory
might be abbreviated, so substring does not work correctly. For example, on
my system (Windows) the default value
is "c:/Users/HECTOR~1/AppData/Local/Temp/". It ended up trying to delete my
source directory (!), but fortunately permission is denied.
A workaround is to manually set temporary-file-directory in .emacs to the
correct full path.
Regards,
Hon

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
I've now made this change in Emacs 29, but even so, it looks somewhat
unsafe to me -- there probably should be more checks here, but I'm not
that familiar with flymake.

I'm unable to reproduce this problem, but perhaps the fix proposed by
Lian Hung Hon also fixed what you're seeing here? Are you still able to
reproduce the problem with the current Emacs 29?

More information was requested, but no response was given within a
month, so I'm closing this bug report. If the problem still exists,
please respond to this email and we'll reopen the bug report.
