### Question:
TableReaderMetadata extends BaseRecordMetadata implements Closeable { public static void freeTransitionIndex(long address) { if (address == 0) { return; } Unsafe.free(address, Unsafe.getUnsafe().getInt(address)); } TableReaderMetadata(FilesFacade ff, Path path); static void freeTransitionIndex(long address); void applyTransitionIndex(long pTransitionIndex); @Override void close(); long createTransitionIndex(); @Override int getColumnCount(); int getPartitionBy(); int getVersion(); void cloneTo(AppendMemory mem);  }### Answer:
@Test public void testFreeNullAddressAsIndex() { TableReaderMetadata.freeTransitionIndex(0); }
