I would possibly store the data to RMS and then force a quit of the
application or something, so the second time its run, there is no memory
leak.

Here's the report from j2mepolish on the bug..

When you call getResourceAsStream() memory will be leaked in the same size
as the resource. This is also the case when it is used indirectly, e.g. in
Image.createImage().

Cheers
