The Manager/Store component can't easily determine if it is being

The root cause here is configuration error - configuring multiple web

Thanks for the explantation!
Suggestions for StandardManager.file() :
- allowing a directory as absolute pathname:
if (file.isAbsolute()) {
if (file.isDirectory()) {
var contextName = getContext().getBaseName();
return new File(file, "SESSIONS-" + contextName + ".ser");
- a quite ugly code to detect bad usage:
static Map<String, String> pathname2contextName = new HashMap<>();
...
if (file.isAbsolute()) {
var contextName = getContext().getBaseName();
var prev = pathname2contextName.get(pathname);
if (prev != null && !prev.equals(contextName)) {
log.error("You can not share same absolute \"pathname\" for
multiple <Manager>s (found same \"pathname\" for " + contextName + " and
" + prev + ")");
}
pathname2contextName.put(pathname, contextName);
This will likely cause issues with parallel deployment.
If anything, this ought to be a non-fatal warning, and potentially under
a logger used exclusively for this purpose so it can be disabled if the
operator knows what they are doing.
