Research direction

Examine the file jpeg stream wrappers.cpp at line 135. The issue is that NewByteArray can return null, and the code should check for that before using the array. Implement a null check and handle the error appropriately, following the existing error handling patterns in the codebase (e.g., return an error code or throw an exception). Look at nearby code for examples of null checks on JNI objects.
