Description
The issue involves incorrect handling of maximum integer values in openapi-yaml. The core issue resolves around not handling of upper half of unsigned 64 bit value i.e. (2^63 to 2^64-1).

The following code pointer is causing the change
should be changed to
if (maximum != null) {
if (isIntegerSchema(schema)) {
target.setMaximum(String.valueOf(maximum.toBigInteger().toString()));
} else {
target.setMaximum(String.valueOf(maximum.toBigInteger().toString()));
}
if (exclusiveMaximum != null) target.setExclusiveMaximum(exclusiveMaximum);
}
