## IMPORTANT WARNINGS

1. APIs marked with the `@Beta` annotation at the class or method level
are subject to change. They can be modified in any way, or even
removed, at any time. If your code is a library itself (i.e. it is

    // for each exception
    // - knowing what artifacts are missing
    // - project building exception
    // - invalid project model exception: list of markers
    // - xmlpull parser exception
    List<Throwable> getExceptions();

  // Release any underlying resources, including the interface object.
  //
  // WARNING: The destructor of this class is marked as protected to disallow
  // clients from directly destroying this object since it may manage its own
  // lifetime through ref counting. Thus clients MUST call Release() in order to
  // destroy an instance of this class.

## Deprecate a *path operation* { #deprecate-a-path-operation }

If you need to mark a *path operation* as <abbr title="obsolete, recommended not to use it">deprecated</abbr>, but without removing it, pass the parameter `deprecated`:

{* ../../docs_src/path_operation_configuration/tutorial006_py39.py hl[16] *}

It will be clearly marked as deprecated in the interactive docs:

        assertThrows(SmbUnsupportedOperationException.class, sut::watch);
        verify(tree, times(1)).close();
    }

    // SMB1 path: on error code 0x10B the handle should be marked closed
    @Test
    @DisplayName("watch() SMB1 marks handle closed on error 0x10B")
    void watch_smb1_marksClosed_onError10B() throws Exception {
        NotifyResponse resp = mock(NotifyResponse.class);
