Windows 7 32-bit, Jenkins LTS (1.596.2), Mantis v1.2.19
My installation has been working for some years now.
I upgraded mantis plugin from 0.25 to 0.26 yesterday.
Today I modified job and project/category shows me only "-".
As soon as I open an exisiting job I see values from xml config file for a short time and it switches to "-".
After upgrade I downgraded plugin back to 0.25 and it still the same.
I compared config files from "hudson.plugins.mantis.MantisProjectProperty" (using config backup plugin) and they are byte identical.
I did not modified mantis install the last months.
So I ran out of idea.
Tried to log something using logger "jenkins.plugins.mantis", but it is empty.
Any ideas?
[JENKINS-28381] My mantis plugin does not show me any project and category
> Tried to log something using logger "jenkins.plugins.mantis", but it is empty.
you have to use logger "hudson.plguins.mantis", not "jenkins.plugins.mantis".

added a comment - Hello, have you seen my last posting from today?
There was one log message.
But for sure I will change logger like recommended from you and will come back tomorrow.

Got a lot more log messages now 
Here we go. Just opened one job config and got:

Looks like connection is ok and list of projects and categories has been received.
Could this be an issue of latest java 8 u45 update? That's all I remember doing the last weeks.

We are using mantis and jenkins a lot and would appreciate any help.

added a comment - Spent some more time and have it working again.
What I did:
- Removed mantis plugin 0.26
- Restarted jenkins
- Installed mantis plugin 0.25 (hpi file from archive)
- Restarted jenkins
- Entered mantis user credentials again
- Restarted jenkins
- Configured job and now project and category Combobox has entries again.
I am happy so far.
Bad side: I will not upgrade to 0.26 and further releases due to named problems.
I am willing to support plugin devs in testing. Just let me know.

Jenkins version and mantis plugin version is the same.
Just compared their config to the working ones from a week ago and they are binary identical.
Log looks like in my previous posting.
What we have done: We rebooted our window machine.
Any hints for me?

Any hints for me? Still not working. Made another observation:
We have many jobs with "update ticket at mantis" as post build action. These jobs are untouched for a while and so they have valid project and category ids.
Whenever such a job should update ticket my jenkins log says:

Does this help in any way to find the cause of my problems? I finally found the cause.
On mantis we have a plugin called "Reminder" to send out due date notifications. As soon as this plugin is active the trouble starts. Tried it now a few times and behaviour is reproducible.
Openend ticket at mantisbt. Link: https://www.mantisbt.org/bugs/view.php?id=19848
You can close this issue from my side.
Plugin loads language file which is UTF8 with BOM. As soon as I remove BOM connection works fine.

Any ideas?
Just upgraded LTS version to Jenkins ver. 1.596.3 but no success.
There is only one log entry:
