HOW

ゴール: verify AtomicLongDeserializer in pkg:maven/com.fasterxml.jackson.core/jackson-databind@2.21.4
パッケージ: com.fasterxml.jackson.core/jackson-annotations 2.21

com.fasterxml.jackson.core/jackson-core 2.21.4

com.fasterxml.jackson.core/jackson-databind 2.21.4
シンボル: AtomicLongDeserializer
com.fasterxml.jackson.databind.ObjectMapper.readValue
com.fasterxml.jackson.databind.DeserializationFeature.ACCEPT_FLOAT_AS_INT
com.fasterxml.jackson.databind.cfg.MutableCoercionConfig.setCoercion
環境: java 21
作成日: 2026-08-18T13:03:47Z

assert numeric string above Integer.MAX_VALUE deserializes to AtomicLong without 32-bit truncation
assert floating-point token above Integer.MAX_VALUE preserves the 64-bit integral value under ACCEPT_FLOAT_AS_INT
assert negative numeric string below Integer.MIN_VALUE preserves negative 64-bit value
assert large integral token near Long.MAX_VALUE deserializes to AtomicLong and bean property
assert disabling ACCEPT_FLOAT_AS_INT rejects floating-point input
assert configuring integer String coercion to Fail rejects quoted numeric string
