Forge MDK runClient崩溃，可能是因为LWJGL。我怎样才能修好它？

Question

我尝试构建1.12.2 MDK附带的示例模块，gradlew setupdecompospace，gradlew eclipse，甚至gradlew build都可以正常工作，只有当我尝试运行gradlew runClient时，它立即崩溃并打印以下错误/堆栈跟踪：

系统信息：

• 操作系统：Ubuntu 18.04

不过，我仍然可以从发射器上运行（改装）雷舰，而不会出现此错误。

Answer 1

我使用

export _JAVA_OPTIONS='-Dsun.java2d.opengl=true'

Answer 2

我也有同样的问题。这个问题似乎是同一个问题，所以我尝试了它给出的修复方法——从Java1.8_242降级到1.8_232。虽然很难找到正确的java版本（它在OpenJDK.net上），但它仍然有效。尝试使用Java1.8_232运行gradle。
