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

首先，在 macOS Ventura 上使用 Visual Studio Code 1.81.1、Java extension 1.21.0 和嵌入式 JDK 重现该故障。然后检查 SemanticTokensHandler.getAst 和 full，以及堆栈跟踪中显示的 JDTLanguageServer 调用点；当编辑器更改能够同步，并且 semanticTokens/full 不再产生所报告的内部错误时，即表示完成。
