这是官网的写法: Java SE Development Kit 21.0.8 downloads JDK 21 binaries are free to use in production and free to redistribute, at no cost, under the Oracle No-Fee Terms and Conditions (NFTC).
JDK 21 will receive updates under the NFTC, until September 2026, a year after the release of the next LTS. Subsequent JDK 21 updates will be licensed under the Java SE OTN License (OTN) and production use beyond the limited free grants of the OTN license will require a fee.
严格翻译的话,似乎收费的只有“Subsequent JDK 21 updates”,只要不更新就不收费,问了几个大模型也都这么说。 但是在网上搜索,似乎是按时间收费的说法居多,即三年免费期一过就会开始收费。
