Upgrade to OCI Java SDK version 2.72.0 if you are currently using 2.66.0.
The OCI Java SDK version 2.66.0 contains a bug that causes it to buffer streams unnecessarily. For example, if you upload a stream of size 1 GiB, this will cause the OCI Java SDK to buffer an additional 1 GiB in the heap. This additional memory demand may cause an OutOfMemoryError.
The latest safe version is 2.65.1.
OCI Java SDK 3.x is not affected.
You are affected if:
you use version 2.66.0
and you use the Apache Connector (which is the default connector in the OCI Java SDK)
and you upload streams (e.g. using Object Storage's putObject or uploadPart operations)
