Issue with ConnectioPoolIntrospection

Hi Team,

we are using the Dynatrace 7.1, I know Dynatrace 7.1 support has been approaching to the EOL but wondering if this issue still exist or not in newer release. We are migrating to Dynatrace 7.2 but there is license issue and for which separate communication happening with Dynatrace team. Meanwhile, we required to resolve this issue.

For now, i have excluded "ogr.apach.tomcat.dbcp" package for smooth process. But, required concrete solution.

Issue is; i am getting below error in thread dump

"IM Trigger Scheduler" tid=0x47 in RUNNABLE

Blocked: 2808[-1ms], Waited: 2159[-1ms]

User CPU: 11m43s

And i could see the below warning messages in agent log file :

2019-07-03 01:51:20 [00006650] warning [java ] ... last message repeated 1 time ...

2019-07-03 01:51:20 [00006650] warning [java ] [jdbc ] DBCP transformStatement 2: java.lang.NoSuchFieldError: _conn



and after sometime application gets hung. Would you please guide me on this.

Thank You

I'm not sure if this is related, but is your performance werehouse connection working fine? I'm asking because of JDBC issues.
