Summary

Cleans up the 16 javac deprecation warnings that appeared when the project moved to Java 11.

Details

Replaces deprecated AWT input APIs with their non-deprecated equivalents:

• Toolkit.getMenuShortcutKeyMask() → getMenuShortcutKeyMaskEx()
• InputEvent.{SHIFT,CTRL,META}_MASK → *_DOWN_MASK
• KeyEvent.getModifiers() → getModifiersEx() in FindToolBar's key listener
• FindToolBar's JButton ActionEvent modifier check now uses ActionEvent.CTRL_MASK|SHIFT_MASK, which are not deprecated and have the same values as the old InputEvent masks

KeyStroke.getKeyStroke(int, int) accepts both the old and extended modifier masks, so keyboard shortcuts are unchanged.

Test plan

./gradlew clean build passes with no javac warnings. Manually verify in the demo app (./gradlew RSTAUIDemo:run):

• Ctrl/Cmd+F focuses the search field in the Find and Replace dialogs
• Shift+Enter and Ctrl/Cmd+Enter in the dialogs search backward
• In the Find toolbar, Enter searches forward and Shift+Enter / Ctrl+Enter searches backward
• Ctrl/Cmd+Shift+F and Ctrl/Cmd+Shift+H show the toolbars, and Ctrl/Cmd+L opens Go To Line
