Eric,

My apologies. I dropped the ball on this one. I've just re-read the thread to remind myself of the details. I'm aiming to get this fixed for the November release round.

Hi Mark,

Just following up on this. Did you arrive at the long-term solution? This issue 
is still biting us.

OK.

This is an interim binary patch for 9.0.80 only.

The purpose is to:
- confirm the proposed change fixes the problem
- provide you with a workaround in the short term

This is the binary patch:

https://people.apache.org/~markt/dev/classloader-not-found-cache-9.0.8
0-
v1.zip

Extract the contents into $CATALINA_HOME/lib

You should end up with:

$CATALINA_HOME/lib/org/apache/...


I'll get on this right away.

Usual caveats apply. This is not an official release. Use it at your
own risk. Don't blame either me or the ASF it is results in alien
invasion, a tax bill, the server catching fire or anything else unexpected 
and/or unwanted.


Okay, but if we're invaded by alien tax collectors riding flaming servers, THEN 
I'm coming after you.

Longer term, I'm not sure this is exactly how I want to fix it in
Tomcat. I am convinced of the need to cache classes that don't exist
but exactly where / how to do that and what degree of control the user should 
have is very much TBD.

I suspect this will be a topic of discussion at Community Over Code at
Bratislava next week.

I am expecting that any fix won't be in the June release round but
should be in the July release round.

Let us know how you get on and good luck.


Will do!


Mark

One of the webapps is related to voice reminder messages that go
out to people. The reminders go out sometime after 9 am, which
tracks with the slowdowns.

Ack.

Something to try while I work on a patch is setting
archiveIndexStrategy="bloom" on the resources.

You'd configure that in META-INF/context.xml something like this:

<Context>
    <Resources archiveIndexStrategy="bloom" /> </Context>
