String Out Of Bounds Error

Here is the error:

Code:

[23:14:18] [Server thread/WARN]: [INCore] Task #10 for INCore v1.0 generated an exception
java.lang.StringIndexOutOfBoundsException: String index out of range: 1
    at java.lang.String.substring(String.java:1907) ~[?:1.7.0_51]

And here is the onJoin event where the error occurred:

Code:java

Bukkit.getScheduler().runTaskLater(plugin, new Runnable() {
@Override
public void run() {
try {
plugin.Cache.setup(p.getName());
} catch (Exception e) {
e.printStackTrace();
}
 
PermissionUser pp = PermissionsEx.getUser(p);
plugin.impulseusers.put(p.getName(), new ImpulseUser(p.getName(),
pp.getGroups()[0].getPrefix(),
pp.getGroups()[0].getSuffix(),
pp.getGroups()[0].getPrefix().substring(0, 1),
plugin.Achievement.getAchievements(p.getName()),
plugin.Statistics.getStats(p.getName())));
 

Any help on this?

That isn't a full stacktrace.

 

AoH_Ruthless what do you mean?

 

Jbitters3
I thought the stacktrace you provided was incomplete but I took a closer look. Sorry

Not really familiar with hooking into Pex so I can't really help you much. Again sorry.

 

AoH_Ruthless Alright thanks though

 

Code:

pp.getGroups()[0].getPrefix().substring(0, 1),

This is the issue.

 

Absence of debug messages is the issue...

 

ZeusAllMighty11 Yes, I understand that. But what exactly is wrong with that. I do not have this issue when it is not connecting to the database.
