问题反馈与解决方案 #

这个问题在Vaadin社区已有其他开发者反馈，核心原因是Vaadin 23.2.x中ComboBox的数据更新逻辑导致PendingJavaScriptInvocation对象大量堆积未被及时清理，尤其在ComboBox频繁进行数据加载、过滤或滚动操作时更容易触发。

可通过以下方式解决：

• 升级至Vaadin 23.2.10及以上补丁版本，官方已修复该内存泄漏问题
• 优化ComboBox数据加载策略：启用分页加载、减少单次加载的数据量，避免频繁触发大量JS调用
• 组件卸载时手动清理：在UI销毁或ComboBox移除时，调用UI.getCurrent().getPendingJavaScriptInvocations().clear()清理未完成的JS调用（注意线程安全）
• 临时调整JVM内存参数缓解问题，但这仅为治标方案
