public class Box
extends JComponent
implements Accessible

Emulator for Box. Container with a pre-installed BoxLayout plus static factories producing the canonical Box.Filler components migrators reach for: horizontal/vertical glue, struts, and rigid areas.

R_leaf_peer_lockdown-locked-down — JDK Box is a leaf in the public javax.swing.* hierarchy. Peer is a plain Div; the protected (Component peer) ctor is omitted so user-code subclasses inherit the locked Div peer.

Emulator-only — no SBox surrogate by SD_no_sjoptionpane-shape carve-out (the JOptionPane "no surrogate by design" precedent). Pure-surrogate users have no use for Box: Vaadin's VerticalLayout / HorizontalLayout cover the same ground without the JDK ergonomic lift.

setLayout(LayoutManager) throws. JDK Box always throws AWTError from setLayout — the layout is fixed at construction time and the ctor bypasses via super.setLayout. R_match_swing_errors: we match the same throw, same message.
