^^^^ that’s due to

Now I didn't face the NPE when switching single mode to multi-mode with lucee version 6.0.0.480-SNAPSHOT. But when trying to switch the mode repeatedly, the single mode switch option was not worked, and can't able to switch to the multimode. After the refresh, it works fine.

i found that the ResourceAppender (used by log4j to write to files) not closes the stream when stop is called.

i have a good feeling that this resolves the issue, for sure it is an improvement.

issue is for sure releasing the log, so most likely in only hapening when you switch from multi to single and back to multi. because only then you try to aquire the web log that was already aquired before.

the config object never really had to release unless you do a restart of Lucee.
