[JENKINS-64367] Multibranch directory path length restriction not working properly

Two days ago we updated Jenkins from 2.202.4 to 2.249.3.

Alongside, we updated the WMI plugin to 1.7 as well as the Bitbucket branch source plugin to 2.9.4.

Now the setting jenkins.branch.WorkspaceLocatorImpl.PATH_MAX sometimes is no longer picked up by some of the nodes - while other still respect the setting.

I dumped both 'System information' into my compare tool. No changes could be found besides the obvious ones, e.g. hostname.

Tried to reconnect both nodes. However this did not change anything.

Remark:

After updating Jenkins + WMI we had to manually delete the jenkins.exe.config file on all WMI agents to be able to connect them. Maybe this is related?
