Errors in MacOS makes editor out of sync

Editor in MacOS stops synchronizing changes, does not update errors, etc. In output of Launguage Support for Java I see the following errors:

Cannot invoke "org.eclipse.jdt.internal.compiler.lookup.MethodBinding.isStatic()" because "this.binding" is null
java.lang.NullPointerException: Cannot invoke "org.eclipse.jdt.internal.compiler.lookup.MethodBinding.isStatic()" because "this.binding" is null

Environment

• Operating System: MacOS Ventura 13.4.1
• JDK version: embedded
• Visual Studio Code version: 1.81.1
• Java extension version: 1.21.0

まず、macOS Ventura 上で Visual Studio Code 1.81.1、Java extension 1.21.0、組み込みの JDK を使って失敗を再現します。次に、SemanticTokensHandler.getAst と full、およびスタックトレースに示されている JDTLanguageServer の呼び出し箇所を調査します。エディターの変更が同期され、semanticTokens/full が報告された内部エラーを生成しなくなれば完了です。
