#1 Updated by Ovidiu Maxiniuc over 5 years ago

Recently, the AW client running as virtual desktop just froze. The only clue I found was in client log: 

Exception in thread "WebRepaint" java.util.ConcurrentModificationException
    at java.util.LinkedList$ListItr.checkForComodification(LinkedList.java:966)
    at java.util.LinkedList$ListItr.next(LinkedList.java:888)
    at com.goldencode.p2j.ui.client.gui.driver.web.GuiWebSocket.sendPendingDrawingOps(GuiWebSocket.java:1605)
    at com.goldencode.p2j.ui.client.gui.driver.web.GuiWebEmulatedWindow.drawOnScreenBitmap(GuiWebEmulatedWindow.java:814)
    at com.goldencode.p2j.ui.client.gui.driver.web.GuiWebDriver$RepaintThread.run(GuiWebDriver.java:2111)

I guess these are rare cases. The cause seems to be the accesses to hoverableWidgets of GuiWebSocket not being synchronized in any way.
