JoinHow to find generics when running a java process
I'm generating code out of code. To do this I need to scan code to generate the code, this includes generics. Currently I'm using classgraph as the scanner for the code, but it does not look like it supports generics (I believe it's runtime, so generics don't exist there).
Does anyone know a way to programmatically fetch generics from a library?...

Java Swing window not showing
I have uploaded 2 .java files one is
ShapedWindow and second Window. When running ShapedWindow the window appears as expected and UI works. ShapedWindow is basically few copypasted snippets together, so I wanted to rewrite it with Anonymous class overriding JPanel as seen in Window class but when running that, GUI does not show up, as if the call to display does not happen. Since biggest change was the Anonymous class I would be looking for issue there but I am not sure what exactly I am looking for.
Is there a way of doing this better?...AWT window coordinate system
What coordinate system does awt use when you set a size of a frame? Does it use screen- or pixel coordinates? Because if I create a window of the same content size with glfw the glfw window is smaller. And yes I know that awt includes the decorations in the size of the window

Creating a gradle plugin for a custom JVM language
Hi!
I'm currently struggling making a gradle plugin for a simple JVM language I've made.
The goal is to make my language buildable using gradle with the least user configuration as possible.
I already read this article on sorcersoft, this one on baeldung and this one from dzone.
I also read the official gradle documentation....

Populate Spring Data JPA before each @Test
I want to test my Products repository (or other tests that requires database to be populated first). I have tried using
ApplicationListener<ApplicationReadyEvent> previously but even though (in the testing environment), the populating methods seem to have been run, the .save methods called by them returns null for each data creation when populating.
My goal is to have the database bootstrapped with the data I have parsed from my CSV parser so it can be used as a Test resource. I have tried so many things, but yet none of them automatic populators work, for it to work, I have to manually populate the data explicitly before tests in the test environment.
