get vsimem file byte array while using java binding #11192

Feature description

i have saved a dataset to png file.

file = "/vsimem/output.png";
out_drv.CreateCopy(file, dstile, 0, new String[0]);

then i want to get the file's byte array and save the bytes to database.

In C++ gdal，VSIGetMemFileBuffer can convert /vsimem/** file to byte[], but I can not find corresponding method in java gdal. What can I do to use it in java?

Additional context

using gdal 3.6.3
