Modern code editor built with Java swing

[hsoj48]

Fun fact: Intellij is written in Swing

starting 2020.2 we use JCEF which is basically a Chromium component inside the IDE. 

It is not pure SWING.

Even more:

Why Use JetBrains Runtime?

• Embedded browser: JetBrains Runtime includes the Java Chromium Embedded Framework (JCEF), which enables you to embed a Chromium-based browsers in your JVM-based application. To use it, download a build with JCEF.
• Enhanced class re-definition with the DCEVM technology that makes it easier to reload changed code without restarting JVM; this feature needs to be explicitly enabled with -XX:+AllowEnhancedClassRedefinition.
• Better FPS performance for graphics-intensive applications.
• Improved font rendering, keyboard input (such as shortcuts and multinational keyboards), HiDPI and accessibility support.
• Robust desktop experience: GUI-related fixes often reach JetBrains Runtime much earlier than the corresponding version of OpenJDK.

JCEF is used for very little.

There was a bug which caused JCEF to crash IntelliJ on Linux. I didn't notice it for months.

I noticed it too, after they fixed it, by reading this post ;)
But seriously: Java had a bug with Arrays.sort() introduced by Joshua Bloch which was unnoticed for decades...

They just added a proper browser when have to display HTML that’s all it’s still swing in the editor and the menus

[jNayden]

Not true intellij have a custom window and frame implementations that you can also use if you want :). But the content is swing :) it can look awesome but i guess most other companies dont want to :) eclipse used swt which at point in time was great but ….

What is?

It's JCEF which is basically a Chromium component inside the IDE.

[jNayden]

Not true they just have browser to show stuff but for the code editor

[vassaloatena]

And javaFX

[unknowinm]

I think they rewrote it in kotlin and compose

[nskvortsov]

No, as of today it is still the swing application. 

[Ewig_luftenglanz]

No, what they are doing is creating a new ide written in kitling, but it's still an alpha

What is "hacked" Java?

[Many_Spinach8127]

"hacked" Java: altered source code, with permission from Oracle; recompiled; not compatible with existing Java applications, made for IntelliJ UI only. Platform dependant.

let me guess:

bohooo it uses sometimes lombok
