Description: What's Changed The Direct Buffer is not always needed to use Arrow memory, however, we cannot load MemoryUtil class if we don't set: --add-opens=java.base/java.nio=org.apache.arrow.memory.core,ALL-UNNAMED Which is not always needed/possible. This fix proposes to catch the InaccessibleObjectException to not avoiding the load of the class. The directBuffer is, in any case not available and a UnsupportedOperationException will be throw as it is in the existing code Closes #1007 .
