I created a variation of a basic TNT cannon where a dispenser launches fireworks into the water stream, thus sending them horizontally. If the flight duration of the rockets are 1, there is no problem. If the duration is 2 or 3, the firework will disappear after a short distance and the game will lag out to the point of crashing. Launching fireworks from the dispenser in a vertical direction also works fine.

If it's not generating a crash report, we will need the game output in that case.
Please attach the complete output of the "Game Output" which can be found on the fourth tab of the launcher.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".
Confirmed for
1.8.7 when a firework flies horizontally in unloaded chunks
Example command
/summon FireworksRocketEntity ~ ~1 ~ {LifeTime:99,Motion:[10.00,0.00,0.00],FireworksItem:{id:401,Count:1,tag:{Fireworks:{Explosions:[{Type:0,Flicker:0,Trail:0,Colors:[1234],FadeColors:[1234]}]}}}}Generated with: http://www.minecraftupdates.com/fireworks
