cfml

I am trying to upgrade a site to ACF2021 Update 6, and getting this error on site start:
```'long javax.servlet.http.HttpServletRequest.getContentLengthLong()'```
This is a result of using `cfthread` , something simple as this blows up:
```&lt;cfthread action="run" name="anything"&gt;&lt;/cfthread&gt;```
I can dish more details but I am hoping this is a known issue with threads in 2021 and there is a quick fix? :pray:

You posted a class/method name, but that's not really an error :thinking_face:

The exception is
```java.lang.NoSuchMethodError: 'long javax.servlet.http.HttpServletRequest.getContentLengthLong()' at coldfusion.thread.HttpServletRequestWrapper.```
Some trial and error revealed that a mapped AppDynamics folder of JARs added to the `app &gt; libDirs` of `server.json` was the issue. There must be a conflict with one of the Adobe natives. Which one of those JARs is the problem I am not sure, but it's not Adobe and not cfthread. I need to go chase that down. :cry:
