We had apm working in an app, which is built on Lucee CFML ([https://lucee.org/](https://lucee.org/)) . Which is a scripting language on the JVM. The app runs in tomcat, but because the script engine only exposes a single servlet we need to set a custom transaction name in the app. This was working fine with earlier version of apm, but upgrading to 1.0.1 seems to have broken it and we now get an error in the logs. Heres some details In our onRequestStart handler we do ```auto ElasticApm.currentTransaction().setName(txName); ``` Where `ElasticAPM` is a singleton instance of the `co.elastic.apm.api.ElasticApm` . Previously that was all we needed, and we got our custom tx name in apm. Now however, we still get data in apm, but all transactions are named `CFMLServlet#doGet` or `CFMLServlet#doPost` etc In the server logs/console we get the stack trace below. I've truncated the trace, but it starts from /Application.cfc:129, which is the location in our code where we call `ElasticApm.currentTransaction().setName(txName);` If this is better posted on github, then happy to move it over there [edit] I forgot to add environment info ```auto openjdk version "1.8.0_181" Apache Tomcat/7.0.59 ``` ```auto 2018-11-27 10:40:14.471 [http-bio-8080-exec-9] WARN co.elastic.apm.bci.bytebuddy.ErrorLoggingListener -

Could it be that you are using an older version of the [`apm-agent-api`](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#public-api) module? Updating that to the latest version should fix the problem. ---

no, we're using elastic-agent-api 1.0.1 and the same version of the agent ---

Hmm, that's somewhat strange 🤔 > [@Chris\_Blackwell](#): > > `java.lang.IllegalStateException: Cannot locate field named span for class co.elastic.apm.api.TransactionImpl` In version 1.0.1, there is actually a span property in `TransactionImpl`'s superclass `SpanImpl`: > However in previous versions, there was no property called `span`, as it was called `transaction`. > Could you double check that you are using the current version of this artifact: [Maven Central Repository Search](https://search.maven.org/search?q=g:co.elastic.apm%20AND%20a:apm-agent-api) ---

My bad. I did a `find ./src | grep apm` and it spat out an old jar in a lib directory where it had no right to be hiding. Now works as expected, thank you! However,I do get the following warning on the first request ```auto 2018-11-29 21:55:17.668 [http-bio-8080-exec-1] WARN co.elastic.apm.bci.bytebuddy.ErrorLoggingListener - ERROR on transformation lucee.runtime.net.http.HTTPServletRequestWrap java.lang.IllegalStateException: Cannot resolve type description for javax.servlet.http.HttpUpgradeHandler ``` The src for that class would be here - [https://github.com/lucee/Lucee/blob/master/core/src/main/java/lucee/runtime/net/http/HTTPServletRequestWrap.java](https://github.com/lucee/Lucee/blob/master/core/src/main/java/lucee/runtime/net/http/HTTPServletRequestWrap.java) ---

Warnings with the message `Cannot resolve type description for` are not something to worry about. The reason in this case is that Tomcat 7 ships with the Servlet API 3.0, but [HTTPServletRequestWrap.java](https://github.com/lucee/Lucee/blob/master/core/src/main/java/lucee/runtime/net/http/HTTPServletRequestWrap) referrrs to classes of the servlet api 3.1, which are not present in Tomcat. ---

This pull request should remove the warning for that as it does not try to resolve the missing class anymore: [https://github.com/elastic/apm-agent-java/pull/363](https://github.com/elastic/apm-agent-java/pull/363) To get notified of the next release, go to [https://github.com/elastic/apm-agent-java](https://github.com/elastic/apm-agent-java), click on watch and select "Releases only". Thanks for reporting! ---
