Describe the bug, including details regarding any error messages, version, and platform.
When appending a variable width vector to another in Java, it computes the size of the currently appended vector by just taking its end offset. It never subtracts the start offset because the majority of start offsets are 0. However, if another language slices a buffer and passes it to Java, it may have a non zero starting offset. This causes us to drastically overestimate the amount of memory to allocate and can cause errors downstream.
