cfsavecontent & cfinclude - java.util.ConcurrentModificationException

Description

Multiple requests are running in the same millisecond.
Code:
226 <cfsavecontent variable="viewContent">
227 <cfinclude template="#viewPath#" />
228 </cfsavecontent>

Lucee error:
/home/wwwroot/contens/framework/eventcontext.cfc (227)

failed to load template /home/wwwroot/contens/ui/views/baseframe/section_content.cfm
java.util.ConcurrentModificationException

So I guess cfinclude and/or cfsavecotnent is not thread safe?

Environment

Windows 10

Micha,
Does this include even if you are NOT using cfthread?

as you can see in the comments and the status of the ticket. i could reproduce and solve it.

MIch,
I know you stated you could not duplicate this issue and it does make sense it is a threading issue since I do use threading quite a bit. I did notice that after removing the cfsavecontent and just doing the include that my errors decreased significantly. i was getting 30+ restarts of my servers each day when the search engines were indexing us. After removing that it dropped to a couple of them. Is it possible that there is still an issue with cfsavecontent since I do use that everywhere in my functions for my rendered html to return it from the cfc's?

Edited

following testcase forces the issue every time, not in exact the same way, but still the same issue:

<cfset AMOUNT_OF_TRIES=200> <cfsetting requesttimeout="2000"> <cfloop from="1" to="#AMOUNT_OF_TRIES#" index="i"> <cfthread action="run" name="t#i#" key="t#i#"> <cfloop from=1 to=1000 index="y"> <cfset request["y"&y]=""> </cfloop> </cfthread> </cfloop>
Fixed
