You don't need `sensitive(false)`. I think you'r safe to remove it from
these new properties.

> Affects Versions: 1.8.0
> Reporter: Colin Dean
> Priority: Major
> Labels: DBCP, database

> While investigating a fix for NIFI-5789, I noticed in the [DBCPConnectionPool
> documentation|https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-dbcp-service-nar/1.8.0/org.apache.nifi.dbcp.DBCPConnectionPool/index.html]
> that NiFi appears _not_ to have controller service configuration options
> associated with [Apache
> Commons-DBCP|https://commons.apache.org/proper/commons-dbcp/configuration.html]
> {{BasicDataSource}} parameters like {{minIdle}} and {{maxIdle}}, which I
> think should be both set to 0 in my particular use case.
> Alternatively, I think I could set {{maxConnLifetimeMillis}} to something
> even in the minutes range and satisfy my use case (a connection need not be
> released _immediately_ but within a reasonable period of time), but this
> option is also not available.
