Description

Follow-up after https://issues.apache.org/jira/browse/ARROW-2249: Currently only primitive arrays are supported in pyarrow.Array.from_jvm as it uses pyarrow.Array.from_buffers underneath. We should extend one of the two functions to be able to deal with string arrays. There is a currently failing unit test test_jvm_string_array in pyarrow/tests/test_jvm.py to verify the implementation.
