[Crash] ECC Minimap

Minecraft Username:
314

Brief Description:
Crashing when attempting to join any entry from the multiplayer list. I don't know whether it only happens with Spigot, or also with vanilla. (Tested with localhost and ECC.)

I came across this bug a few months ago, then gave up fixing it. Now I am trying to use the Minimap again and am still experiencing this bug.

Instructions:

1. Install the latest version of Forge available.
2. Place the latest version of the ECC Minimap in mods/1.8/
3. Attempt to join any entry from the multiplayer tab. Singleplayer worlds work just fine, Multiplayer worlds crash with "String index out of range: -1"

How many times did you recreate this bug?:
80+ times. 100% success rate.

Result:
Crashing.

Expected Result:
Not crashing.

Evidence:

Spoiler

This is a report from an attempt to join ECC. Everything that is not Minecraft itself, Forge or the Minimap jar has been removed before these tests.

Things I am wondering about:

I have no idea why the report states 1.8.0_25 as my Java version. 8u25 is not existent on my PC, Minecraft is actually run with 8u73 here.
This is also the first time that I have seen UCHIJAAAAAA as status of the mods, normally all I see is UCHIJA.

---

EDITED:

A screenshot of the minimap in a singleplayer world.

This should not be intended behaviour in any way...

 

Added screenshot of the map's Singleplayer appearance.

Also adjusted the number of tries from 20+ to 40+.

 

I didn't know what to do with my free time, so I brought my 40+ crashes to 80+ crashes... all attempted with minor variations, nothing works. I set up a completely new testing environment with a clean vanilla MC and the required files only... I no longer have an idea what causes these problems.

 

Latest version freshly downloaded from Jamie's server before testing, no options changed, not modified in any way since I haven't found the time to decompile it for fun yet.

 

Ah, I see - thank you for the answer.

What version of forge is the minimap tested for?

 

I hate to say it, but... I see no changes at all. ;-;

Minecraft 1.8, Forge 11.14.3.1468, Minimap 1.8 2.2.5.

@JamieSinn - Minor update...
I completely nuked my testing folder once again and accidentally cleared (a lot) more than I wanted...
...however, now it "works".

• Things that work now:
  • Joining a server without crashing.
• Things that do not work:
  • The minimap itself... (See the image below)

I have tested some ideas, and I now know why there is so much pink in the map.

The mod paints the entire chunk (except for transparent blocks) pink if there is at least one single block that is placed at or above y = 64.
The mod paints the single block (except for transparent blocks) pink if the block is located at or below Y = 61.
A very high Y coord causes a 3D-like effect between neighbouring chunks.

Placing a block to invalidate the chunk will keep the chunk pink when the block is broken again, unless the chunk is un- and then reloaded.
