我已经使用OpenJDK运行IntelliJ IDEA但是在终端启动IntelliJ IDEA时它向我显示:
$ ./idea.sh
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b24~pre2-1)
OpenJDK Server VM (build 20.0-b12, mixed mode)
WARNING: You are launching IDE using OpenJDK Java runtime.
THIS IS STRICTLY UNSUPPORTED DUE TO KNOWN PERFORMANCE AND GRAPHICS PROBLEMS!
