Java2Demo SegV when screen type is set to BYTE_INDEXED

build : Java2D:09-Sep-98@02:46
app : Java2Demo
machine: 2.5.1, 5.6
hw : sun4u
bit dep: 8bit, 24bit
screen type: BYTE_INDEXED

Steps to reproduce:
1. Launch Java2Demo
2. Change the Global screen type to BYTE_INDEXED

- you should observe a SegV

SIGSEGV 11* segmentation violation
    si_signo [11]: SIGSEGV 11* segmentation violation
    si_errno [0]: Error 0
    si_code [1]: SEGV_MAPERR [addr: 0x30]

        stackpointer=eab908a0
