Getting stuck on blocks while attempting to throw enderpearl

 

I was on a vanilla Minecraft server with my friends and when I threw an ender pearl at the sky, it landed on the obsidian towers of the end. I was stuck there climbing. when i move, i fall obviously but some exploiters can use it. I use no cheats at all, and I was in vanilla Minecraft.

 

PS: I am a game developer too and I do not support pirating by any way! I use cracked server because my friend can't afford minecraft.
