Forge 1.7.10 crash!!! -- Now resolved

[Gunz77]

I just installed the latest forge, and I get the following crash:

I really have no idea what this is, it's never been an issue with past Forge releases.  I've been invited to a private Pixelmon server, and it is running on the latest version. I can't get on if this error persists.

 

Please help!!!

The EAQ didn't help. My specific error is not on there, as far as I can tell.

I'm using Java 7. First thing I checked.

and what is this

  at java.util.ArrayList$Itr.checkForComodification(Unknown Source) ~[?:1.8.0_20]

  at java.util.ArrayList$Itr.remove(Unknown Source) ~[?:1.8.0_20]

[Gunz77]

No idea.

 

the only java between my program files and my program files(x86) is Java/jre7. I said already, first thing I checked.

in the Profile Editor you see

java settings (advanced)

where is your executable set to ?

if you can show a pic

So apparently Java 8 was installed to another location outside my program files folders. I don't remember changing the destination folder location, but I must have. I did a complete uninstall and reinstall of java, and it seems to have resolved the issue. either that, or the java 8 update simply rewrote the files in the jre7 folder. I really don't know what the hell happened, but it seems to be resolved.

 

A bit of constructive criticism on the past few posts: The excessive sarcasm was not warranted. If you want to give advice, don't condescend me like I'm some kid who has no idea how to operate more than just the most basic operations of a computer. Please be aware, I'm not trying to be dickish, just explaining my frustration-amplified thoughts. I'm not butthurt, and normally everything that you guys said would have made perfect sense, and I still thank you for trying to help.
