OutOfMemoryError while downloading in area of Haiti

[Marcus Love]

What steps will reproduce the problem?

1. I had downloaded a lot of the area in Haiti already, starting from the West bit of Jeremie and Cayes and had worked my way East along the South coast and then started working up the Haiti DR border North.
2. Downloading in the area around Saint Raphael and between St. Raphael and Hinche is when the error happened.

What is the expected result? To have the data downloaded.

What happens instead? It looks like it downloaded, but I'm not sure if it did. It gave an error of some sort.

Please provide any additional information below. Attach a screenshot if
possible.

You must allocate more memory to JOSM, for example java -jar -Xmx1024M josm-tested.jar to allocate 1 Gb to JOSM (choose the value you want).
