32-bit or 64-bit application on a 64-bit OS?

We are developing a swing application written in Java, which requires only about 128 MB of memory, and in the near future I do not see that much more memory will be required, for example, 4 GB. Previously, we always provide 3 different editions, one for 32-bit Windows, one for 32-bit Linux, and another for 64-bit Linux, with an installer that includes JRE. The 64-bit version was not used by anyone else a couple of weeks ago, and an OutOfMemoryException was posted because the application consumes 40-50% more memory than the 32-bit version.

My question is, do we really need to provide a 64-bit version for 64-bit Linux if the application never needs to use more than 4 GB of memory? We had a quick test that showed that the 32-bit version also works on 64-bit Linux. But I'm not sure what the cons could be, which we would have, for example. performance and / or compatibility issues?

If your application does not provide improvements for 64-bit operating systems and is compatible with your 32-bit versions, I do not see an immediate need to provide it.
