[Java] Dataflow through object

Hello,

I am getting some false positives with some of my queries, which are usually centered around a source node flowing into an object and then other data from that object flowing into a sink node.

Here is a simple example,

```
env.put(Context.SECURITY_CREDENTIALS, password);
LOG.error("connection error [{}], failover connection to [{}]", env.get(Context.PROVIDER_URL), this.ldapURI.toString());
```
In this case, `password` is a source variable. While `LOG.error` is a sink. However, by having it flow into `env`, it now marks any use of the object as a detection eventough this case has nothing to do with `password`. Is there any way to reduce cases like this?

Thank you
