> I'm working on a project where I need to aggregate a lot of data in memory. To do this I'm using GzipOutputStream backed by org.apache.commons.io.output.ByteArrayOutputStream. After the aggregation is done I eventually will read the data back out. I'm trying to avoid byte[] buffer copies to reduce the memory usage. ByteArrayOutputStream.toBufferedInputStream seems like the perfect way to do this, but it's a private method. I would only call it after I'm done writing to the ByteArrayOutputStream object. Is there any reason I shouldn't use this method? Could it be made public? Thanks!
