i have runescape problems

ok here is the deal, when i play runescape for like 10 min, after restarting my computer, runescape just logs off randomly and i have tried everything, restarting my computer and reinstalling java and internet explorer but runescape works the best after i restart my computer but once it crashes runescape starts crashing more often and more often and idk what to do. when i open the java console, it has an error for every time runescape logged me off. the error read something like this:

Error: T1 - 55,58,42 - 0

Error: T1 - 165,93,141 - 0

Error: T1 - 114,203,238 - 0

or even longer ones like this:

Error: p.H(302776432,-49) | p:84 ff:1323 rb:88 client:668 v:630 v:585 java.lang.Thread.run | java.lang.ArrayIndexOutOfBoundsException: 4620 | T2 - 148,148,148 - 5,2964,3377 - 127,112,0,12,18,

Error: ff:263 rb:88 client:668 v:630 v:585 java.lang.Thread.run | java.lang.ArrayIndexOutOfBoundsException: 160 | T2 - 102,141,141 - 3,2964,3377 - 18,24,96,

This is a support site for java PROGRAMMERS.If you need help with an application then you should seek help from the creators of the application.If you need help with your computer then you should seek help from a technician.
