Thank you for the review, Phil!
I am afraid we cannot create a regression test for this since the issue takes place only in VNC environment. I have added “noreg-hard” to the bug.

>> Problem description:
>> After integration of JDK-8210776  we started to use malloc() function for allocation of XColor array in QueryColorMap() (see multiVis.c). However malloc() does not initialise allocated memory. So if the memory contains some “garbage” we may get incorrect data inside the array. As a result Robot.createsScreenCapture() retrieves incorrect colours.
