Hi, I am having the latest version of Elastic Stack & Java APM agent. Everything is working fine, but when I am open trace sample I always get **No stack trace available** in Span details whereas I would like to get all query details there. Kindly assist. ---

This may be related to spans duration - see the [`span_frames_min_duration`](https://www.elastic.co/guide/en/apm/agent/java/current/config-stacktrace.html#config-span-frames-min-duration) config for details. ---

I have added span\_frames\_min\_duration setting, but still the same. I am getting the below warnings in tomcat catalina.out : 2020-07-29 14:01:39,841 [main] WARN co.elastic.apm.agent.bci.bytebuddy.ErrorLoggingListener - com.mysql.jdbc.ConnectionImpl uses an unsupported class file version (pre Java 5) and can't be instrumented.

Hold on, I am going to extend our support for Java 1.4 bytecode as well, should be quick ---

Can you try the relevant artifact from [this snapshot build](https://apm-ci.elastic.co/blue/organizations/jenkins/apm-agent-java%2Fapm-agent-java-mbp/detail/PR-1317/1/artifacts) and see how it works for you? ---

If your MySQL driver is compile with Java lower than 1.4 - this is expected. If you upgrade the driver to one compiled with 1.4, you need to use the snapshot I provided above, as `elastic-apm-agent-1.18.1.RC1-SNAPSHOT.jar` only instruments classes compiled with 1.5 or higher. If you upgrade the driver to one compiled with 1.5 or higher - it should work. ---
