How to solve exception: No OpenGL context found in the current thread

I am facing with this exception when I using libgdx in Java:

Exception in thread "Thread-12" java.lang.RuntimeException: No OpenGL context found in the current thread.
    at org.lwjgl.opengl.GLContext.getCapabilities(GLContext.java:124)
    at org.lwjgl.opengl.GL11.glGenTextures(GL11.java:1403)
    at com.badlogic.gdx.backends.lwjgl.LwjglGL20.glGenTexture(LwjglGL20.java:348)
    at com.badlogic.gdx.graphics.Texture.<init>(Texture.java:120)
    at com.badlogic.gdx.graphics.Texture.<init>(Texture.java:100)
    at com.badlogic.gdx.graphics.Texture.<init>(Texture.java:92)
    at com.badlogic.gdx.graphics.Texture.<init>(Texture.java:88)
    at Utils.Player$2.run(Player.java:79)
    at java.lang.Thread.run(Thread.java:748)

How can i solve this? I'm using libgdx. line 79 of Player.java: 

TextureRegion textureRegion = new TextureRegion(new Texture("textures/Textures.png"), 50, 15, 4, 4);

In Kotlin:

Gdx.app.postRunnable {

    // Your code in the context of OpenGL

}

You should not use Thread in libgdx actually, it is not recommended to use Thread. Html does not support threading and it will not work at Html. If you must use threading use, 

Gdx.app.postRunnable(new Runnable() {
         @Override
         public void run() {
            // process the result, e.g. add it to an Array<Result> field of the ApplicationListener.
            results.add(result);
         }
      });

To understand what is going on here, check it official document https://github.com/libgdx/libgdx/wiki/Threading
