[Bug]: openjdk17 & 21: java.lang.UnsatisfiedLinkError: cannot locate symbol "libiconv_open" in libsplashscreen.so

[IntinteDAO]

Problem description

When attempting to run a Java application that utilizes java.awt.SplashScreen, a java.lang.UnsatisfiedLinkError occurs. The stack trace indicates that the library /data/data/com.termux/files/usr/lib/jvm/java-17-openjdk/lib/libsplashscreen.so is unable to locate the symbol libiconv_open.

OpenJDK21 also have this issue

What steps will reproduce the bug?

Install openjdk-17 or 21in Termux.

Run a Java application that uses the splash screen functionality (e.g., LateralGM or another Swing/AWT application).

Observe the UnsatisfiedLinkError in the console.

java.lang.UnsatisfiedLinkError: /data/data/com.termux/files/usr/lib/jvm/java-17-openjdk/lib/libsplashscreen.so: dlopen failed: cannot locate symbol "libiconv_open" referenced by "/data/data/com.termux/files/usr/lib/jvm/java-17-openjdk/lib/libsplashscreen.so"...

What is the expected behavior?

The Java application should launch correctly, and the splash screen (if defined) should be displayed without any errors. I believe it's some kind of regression, because it works in the past

I've been able to successfully create a solution to this problem that's working for me. I will upload and link the solution soon, then after a while I will merge it with some other things.
