我正在将应用程序从 Oracle Java 8 升级到 openjdk Java 16，但无法让 ant 任务 javac2 工作。我收到错误
An Ant BuildException has occured: Forms instrumentation failed
以及原因
Class not found: com.intellij.uiDesigner.core.Spacer
完整的错误信息是：

com.intellij.uiDesigner.core.Spacer我可以在中看到课程forms_rt.jar，所以我不明白为什么会出现错误。是因为我使用的是 Java 16 吗？我的想法版本是 212.4746.92。
干杯，
