We believe that JCEF is a great alternative to JavaFX, as it will provide better stability and performance. JCEF is a Java port of the CEF framework for embedding Chromium-based browsers in applications using Swing. This is because using JavaFX (via JFXPanel) for implementing UIs in Swing applications has some known limitations that have been causing performance and rendering issues.Īs an alternative to JavaFX APIs, we are providing new integration with JCEF. Starting with v2020.2, we’ve decided to deprecate support for the JavaFX runtime in IntelliJ Platform plugins. The upcoming IntelliJ IDEA 2020.2 will correctly handle Unicode emoji characters on Linux. IntelliJ IDEA’s NotNull instrumentation for parameters is also supported, so even if there are several parameters, you’re navigated to the appropriate one. The IDE now parses new NPE messages to the exact NPE cause when possible and to move the caret to the relevant position when navigating from the stack trace to the code. To take advantage of it, simply run your program with the XX:+ShowCodeDetailsInExceptionMessages option. One more improvement in this area is better NPE analysis, which is made possible thanks to the implemented support of the Helpful NullPointerExceptions feature ( JEP 358) introduced in Java 14.
In this case, the analysis will not display the paths where a given value cannot appear. For example, you can specify that the target value is null, true or false, enum constant, string constant, or integer constant. You can now filter “Dataflow to here” by target value. Also, in some cases, the IDE may suggest you start a ‘Dataflow to here’ analysis when navigating from the stack trace. Now, we’ve improved this feature to support more exception types, notably ClassCastException and NullPointerException (JEP-358). When you click on the stack trace, the IDE may navigate you to the relevant place where the exception happened (and not simply to the beginning of the line). The IDE will help you find out exactly what happened to cause the variable to have an unexpected value. To make it easier for you to investigate why a Java program is failing, we’ve supplemented exception stack trace analysis with dataflow analysis.
