> DBCPConnectionPool.getConnectionProperties() throws a NullPointerException
> when a dynamic property value resolves to null.
> The method uses Collectors.toMap to collect dynamic properties into a
> Map<String, String>. The underlying HashMap.merge() does not accept null
> values, so when either propertyValue.getValue() (sensitive properties) or
> propertyValue.evaluateAttributeExpressions().getValue() (non-sensitive
> properties) returns null, the collector throws an NPE.
