It's been 3 days that I look on the internet how to fix this on gradle Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXTabPaneSkin (in module com.jfoenix) cannot access class com.sun.javafx.scene.control.behavior.TabPaneBehavior (in module javafx.controls) because module javafx.controls does not export com.sun.javafx.scene.control.behavior to module com.jfoenix On simple idea projects I was adding --add-exports javafx.controls/com.sun.javafx.scene.control.behavior=com.jfoenix --add-exports javafx.controls/com.sun.javafx.scene.control=com.jfoenix --add-exports javafx.base

I'm trying to migrate an application from Java 8 to Java 11. When I try and build the project in IntelliJ I get a package sun.util does not exist error? Any ideas on what's up? Thanks! Packages com.sun.* and sun.* hold internal stuff, and should not be used by thirdparty applications (like yours probably) in general case. Since in java 9 the module system has been introduced, now Oracle "protect" these packages even in compile time. So the obvious way is to get rid of this dependency in your code. Why do they protect? Because they leave the right to themselves to change this stuff, its

If you want to change the keep-alive timeout you can do so using the property jdk.httpclient.keepalive.timeout . However the value is only read once when the class jdk
