scala - 无法识别的选项 : -Xcext. enabled=true 错误 JVM、JRuby、Scala 和 RubyMine

Question

与安装 JRuby 时的某些内容相关的错误确实很有意义。 当使用 RVM 安装 JRuby 时，它有一个需要编译的依赖项，我认为这并不顺利。 哪个依赖我不太记得了。它似乎与 JVM 和 -Xcext 相关。
斯卡拉:

~$ scala
Unrecognized option: -Xcext.enabled=true
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

没有谷歌搜索结果。
我已经尝试了 http://www.scala-lang.org 的最新版本版本 2.11.1并得到了这个确切的错误。
Java版本:

java version "1.7.0_55"
OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

JRuby:
尝试通过 RVM 重新安装 JRuby 并没有要求构建任何依赖项。所以我必须查找-Xcext在线案例并弄清楚。 ...我似乎无法找到问题所在。

~$ irb
Unrecognized option: -Xcext.enabled=true
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

它会影响 RubyMine。我真的很想知道这个问题在哪里嵌入，因为它引起了很多头痛!
安装 JRuby-head

~/.rvm$ rvm install jruby-head
Checking requirements for ubuntu.
Requirements installation successful.
$JAVA_HOME was empty, setting up JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre, if it fails try setting JAVA_HOME to something sane and try again.

Answer 1

听起来你有 -Xcext.enabled=true在 JVM 的选项环境变量之一中，例如 JAVA_OPTS , _JAVA_OPTIONS , 或 JAVA_TOOL_OPTIONS .我假设在某些时候它应该被添加到特定于 JRuby 的环境变量中，但不小心被放入其中一个 JVM 中。
