Description

There's a small issue with how camel-pgevent attempts to check for the presence of the PostgreSQL JDBC driver. It does:

getClassResolver().resolveMandatoryClass("com.impossibl.postgres.jdbc.PGDriver");

 
On Karaf this results in:

java.lang.ClassNotFoundException: com.impossibl.postgres.jdbc.PGDriver
at org.apache.camel.impl.DefaultClassResolver.resolveMandatoryClass(DefaultClassResolver.java:80) ~[59:org.apache.camel.camel-core:2.20.2]
at org.apache.camel.component.pgevent.PgEventEndpoint.initJdbc(PgEventEndpoint.java:93) ~[?:?]
at org.apache.camel.component.pgevent.PgEventProducer.doStart(PgEventProducer.java:67) ~[?:?]

I have a similar issue on WildFly. I think it'd be better to do the lookup using the ClassLoader of the PgEventComponent. This should work fine in most scenarios.
