Appium - Getting a java.lang.RuntimeException: java.lang.NoSuchMethodException: jdk.proxy2.$Proxy9.proxyClassLookup() at PageFactory

I am getting this exception on running an Appium test. The test fails at PageFactory with the exception below.

• This was working fine up until yesterday, my machine got restarted and this error started coming.
• Already tried with latest version of Appium (7.5.1)
• Did mvn clean and refresh, update

Fails here: PageFactory.initElements(new AppiumFieldDecorator(this.driver), this);

Check the version of Java you are using. I downgraded from JDK v16 to v15.0.2 and that fixed the problem.
