It seems to forward the call from this.activate() to the delegee
("this.connection.activate()"). So this is not a endless recursion by itself
(unless "this.connection" points back to "this" or to a chain of delegated
connections looping back to itself. Both should not be the case normally.
I am not sure how often this.connection is actually another delegation
(instanceof), so it might not be called often anyway.

Betreff: commons-dbcp2 source code read
I amd reading code of commons-dbcp2 source, but a piece of codes confused me.
That is
https://github.com/apache/commons-dbcp/blob/master/src/main/java/org/apache/commons/dbcp2/DelegatingConnection.java
of DelegatingConnection.java .
protected void activate() {
closed = false;
setLastUsed();
if (connection instanceof DelegatingConnection) {
((DelegatingConnection<?>) connection).activate();// 615 todo this
line
}
}
((DelegatingConnection<?>) connection).activate();
can this call occur infinite recursive?
best regards!
