ImageUtil appears not to release http connections

[dkit]

After a while my log becomes full of these messages and it just hangs this didn't appear to be an issue in the previous version :
INFO com.gravity.goose.images.ImageUtils - org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for connection
....

at com.gravity.goose.images.ImageUtils$.fetchEntity(ImageUtils.scala:267)

However I was calling ImageExtractor directly and now I'm using com.gravity.goose.Goose.extractContent and it appears to be calling UpgradedImageExtractor ....

It's still happening. I tried increasing the number of max connections but it didn't help. After some checking I found that Scala should be closing these requests automatically. Any ideas on why this is happening?

Note: The StandardImageExtractor also causes this error. I have to downgrade to two versions ago to get rid of this error ...
