# 解决方案
Java（JRE/JDK）的版本过低，升级Java版本到对应版本的最新版本，安装后可卸载对应版本的旧版本。
JDK 下载：
- Oracle JDK (opens new window)：官方的 JDK 下载，下载需登录，商业使用受限
- Adoptium（原AdoptOpenJDK） (opens new window)：广为人知的预建 OpenJDK
- Red Hat OpenJDK (opens new window)：红帽提供的预建 OpenJDK
- BellSoft Liberica JDK (opens new window)：带有 JavaFX 的完整 OpenJDK
