Hello! I get the following error when displaying a message

SEVERE: java.util.ConcurrentModificationException at java.util.LinkedList$ListItr.checkForComodification(LinkedList.java:966) at java.util.LinkedList$ListItr.next(LinkedList.java:888) at org.zkoss.zk.ui.metainfo.PageDefinition.preInit(PageDefinition.java:966) at org.zkoss.zk.ui.impl.UiEngineImpl.createComponents(UiEngineImpl.java:1132) at org.zkoss.zk.ui.impl.AbstractExecution.createComponents0(AbstractExecution.java:346) at org.zkoss.zk.ui.impl.AbstractExecution.createComponents(AbstractExecution.java:307) at org.zkoss.zk.ui.Executions.createComponents(Executions.java:176) at org.zkoss.zul.Messagebox.show(Messagebox.java:176) at org.zkoss.zul.Messagebox.show(Messagebox.java:416) at org.zkoss.zul.Messagebox.show(Messagebox.java:425) at compras.ctrl.apl.AplCotizaReqEnc.onAcceptYes$btnEnviar(AplCotizaReqEnc.java:820) at sun.reflect.GeneratedMethodAccessor2414.invoke(Unknown Source)

The coding is like this Messagebox.show(Labels.getLabel("msgprocPolizasAfectadas"));

can you help me, the error does not always appear
