cannot be cast to class io.appium.java_client.android.AndroidDriver while using EventFiringDecorator

[ChinmayPandaZee]

Description

I'm trying to use the decorator mechanism provided by selenium 4.
But following the doc to decorate the android driver, I get the exception

java.lang.ClassCastException: class jdk.proxy2.$Proxy22 cannot be cast to class io.appium.java_client.android.AndroidDriver (jdk.proxy2.$Proxy22 is in module jdk.proxy2 of loader 'app'; io.appium.java_client.android.AndroidDriver is in unnamed module of loader 'app')

Environment

Java client build version or git revision if you use some snapshot: 8.0.0
Appium server version or git revision if you use some snapshot: 1.22.3
Desktop OS/version used to run Appium if necessary: Mac Monterey
Node.js version (unless using Appium.app|exe) or Appium CLI or Appium.app|exe: Appium.exe
Mobile platform/version under test: android
Real device or emulator/simulator: Both

Details

Please provide more details, if necessary.

Code To Reproduce Issue [ Good To Have ]

AndroidDriver driver = new AndroidDriver(url, driverCapabilities);
driver=(AndroidDriver) new EventFiringDecorator(new MyLIstner()).decorate(driver);

SImilar to Cannot decorate AndroidDriver (probably the same for IOSDriver #1643

It is simillar to Cannot decorate AndroidDriver (probably the same for IOSDriver #1643 @mykola-mokhnach @SrinivasanTarget

[mykola-mokhnach]

this is fixed in master although not yet published

[ChinmayPandaZee]

Is there any workaround for the time being?

I am getting below exception which need to be handled from listeners.
org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: 'POST /element' cannot be proxied to UiAutomator2 server because the instrumentation process is not running (probably crashed). Check the server log and/or the logcat output for more details

Fixed and released: io.appium:java-client:8.1.0

I think the below line still not working after the fix as well.
AndroidDriver driver = new AndroidDriver(url, driverCapabilities);
driver=(AndroidDriver) new EventFiringDecorator(new MyLIstner()).decorate(driver);

@Rabindra184 yes, I also observed the same issue after the latest fix. Please look into this.@valfirst @mykola-mokhnach

[mykola-mokhnach]

The decorator code is completely inherited from Selenium API. @diemol @titusfortner Do you know about any changes that happened recently and may cause the above error?

[valfirst]

It seems this issue is similar to SeleniumHQ/selenium#9416

[WillingSasi]

Also i meet this issue in Appium:java-client:8.1.1，the following is calling code:

WebDriverListener webDriverListener = new CustomListener();
appiumDriver = (AppiumDriver) new EventFiringDecorator(webDriverListener).decorate(appiumDriver);

Caused by: java.lang.ClassCastException: class net.bytebuddy.renamed.java.lang.Object$ByteBuddy$AuHk1O9o cannot be cast to class io.appium.java_client.AppiumDriver (net.bytebuddy.renamed.java.lang.Object$ByteBuddy$AuHk1O9o is in unnamed module of loader net.bytebuddy.dynamic.loading.ByteArrayClassLoader @6af310c7; io.appium.java_client.AppiumDriver is in unnamed module of loader 'app')
