Subject Camel JPA consumer causing Out of Memory when polling table
Date Thu, 31 Mar 2016 13:55:57 GMT
Curious if anyone can shed light on this...

Using Camel JPA to poll Oracle. On startup, high CPU and memory consumption
is observed; profiler shows oracle driver spending A LOT of time in
getColumnIndex(), not much else, ultimately causes OOM. Camel 2.15.3/Java
8/RHEL 7.1
