PIC18 FreeRots and BootLoader

did anyone use FreeRtos with PIC18 and bootloader ?
I'm trying to do this but i have problems with Interrupt Vector remapping.
In particular i'm able to install the Bootloader, to download my application (FreeRtos based)by a serial interface, but it seems that interrupts don't work.
The bootloader i'm using simply use 2 goto expression on address 0x08 and 0x18 for vector remapping;
This is the program memory :
0X08 GOTO 0x508
0X18 GOTO 0x518
In the file port.c i modified :
#pragma code low_vector = 0x08
#pragma code low_vector = 0x508
From the address 0x508 on, i can find the right code.
File C18i.c has been modified so that reset Vector will be base on 0x500.
Any suggest ?
