intellij-idea - 在intellij idea中设置aspectj weaver的编译级别

Question

我向项目添加了简单的注释驱动方面，IntelliJ 无法编译它:

annotation type patterns are only supported at Java 5 compliance level or above

请建议，应该在哪里配置编译级别(在项目设置中，整个项目和所有模块都设置为 Java 6)，在设置->aspectj weaver 中，只能启用 weaver 并查看方面列表。

UPD 该问题与 OpenJDK 有关，因为aspectJ weaver 插件无法正确识别其版本。补丁已提交给维护者。
