elastic apm java agent elastic-apm-agent-1.0.1.jar is not allowing to start our application.

I am trying to integrate it via generic way. The jar is able to integrate but its failing to our application.

[2018-11-23 18:02:02,599] WARN [request-id=] [x-request-id=] AnnotationConfigEmbeddedWebApplicationContext: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'addToQuartz' defined in class path resource [com/../QuartzConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.quartz.Trigger]: Factory method 'addToQuartz' threw exception; nested exception is java.lang.VerifyError: (class: com/mchange/v2/c3p0/impl/NewProxyPreparedStatement, method: executeQuery signature: (Ljava/lang/String;)Ljava/sql/ResultSet;) Illegal type in constant pool

Please let me know if any other information needed?

Hello and thanks for trying out our agent!

Please let me know which version of c3p0 you are using. I am assuming it is quite old, maybe even old enough to have been compiled using a Java 1.4 compiler. If that's indeed the case, there is apparently a problem for our agent in instrumenting such classes.
Fortunately, c3p0 is probably wrapping a JDBC driver, in which case we can still provide JDBC insights by instrumenting the JDBC driver.
Our upcoming bugfix release (hopefully released this week) will include a general fix where agent will just avoid attempting to instrument classes compiled using a compiler of a version older than 5.
So what I suggest is that you now wait for the 1.0.2 version and see what happens with it.

I hope this works out.

Thanks,
Eyal.
