Under OpenVZ the max heap size is considered to be used immediately by the java process. If -Xmx is not specified the default size may be 1 GB or higher, and this often causes java processes to fail under OpenVZ if the memory isn't available.
ca-certificates-java doesn't need that much memory to work properly, limiting the heap to 64M should be enough.
