Hello,
Could you review a fix for jdk14, please?
bug: https://bugs.openjdk.java.net/browse/JDK-8230782
webrev: http://cr.openjdk.java.net/~dmarkov/8230782/webrev.00/
Problem description:
After integration of JDK-8210776 [1] 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.
Fix:
It is necessary to invoke calloc() for allocation of the array as it
used to be before XWD upgrade
Thanks,
Dmitry
