I used to run the same application in Java 1.7. My colleagues upgraded to 1.8 and no longer able to run it.
我曾经在 Java 1.7 中运行相同的应用程序。我的同事升级到 1.8 并且不再能够运行它。
I tested with SUN JDK and now I am on OpenJDK again and that does not help Current JDK openjdk version "1.8.0_40"
我使用 SUN JDK 进行了测试，现在我再次使用 OpenJDK，但这无济于事 当前 JDK openjdk 版本“1.8.0_40”
JAVA_HOME, JAVA_PATH and any other variable seems to point to the correct JDK installation. I have removed all the previous (JDK 1.6 & 1.7 from the OS to be sure that there is no reference to them).
JAVA_HOME、JAVA_PATH 和任何其他变量似乎都指向正确的 JDK 安装。我已经删除了以前的所有内容（从操作系统中删除了 JDK 1.6 和 1.7，以确保没有对它们的引用）。
For some reason GGTS still complains for a wrong JVM. I understand the error might be related to a compiler 1.7 trying to compile files in the 1.8, but I am not sure where this reference is comming from in eclipse.
出于某种原因，GGTS 仍然抱怨 JVM 错误。我知道该错误可能与编译器 1.7 试图在 1.8 中编译文件有关，但我不确定此引用在 eclipse 中的来源。
My Eclipse installation information lists the following under Java:

It's a problem related to jdk8u40, go back to jdku31. It works in that version. I'm running into the same problem both in windows and linux environments.
是jdk8u40的问题，回到jdku31。它适用于该版本。我在 windows 和 linux 环境中都遇到了同样的问题。

Version 1.8.0_40 and 1.8.0_45 has breaking updates with grails. Spring can not copy non-Root methods.
版本 1.8.0_40 和 1.8.0_45 对 grails 进行了重大更新。Spring 不能复制非 Root 方法。
Since the initial posting a workaround has been developed.
自最初发布以来，已经开发了一种解决方法。
aclement commented on Mar 5 Here is the build: http://repo.spring.io/libs-snapshot-local/org/springframework/springloaded/1.2.2.BUILD-SNAPSHOT/springloaded-1.2.2.BUILD-SNAPSHOT.jar
To test it under grails, what I do is go into the grails folder: grails-2.5.0/lib/org.springframework/springloaded/jars
I then rename the spring loaded jar that is there and put in a symlink to the jar above. It used to be that you could just modify the startGrails script to point to the new version, but now due to the forking I find you need to do the symlink thing. Or drop that jar into this folder and rename it to match the expectations of grails (rename it from springloaded-1.2.2.BUILD-SNAPSHOT.jar to springloaded-1.2.0.RELEASE.jar)
克莱门特在 3 月 5 日评论这是构建：http://repo.spring.io/libs-snapshot-local/org/springframework/springloaded/1.2.2.BUILD-SNAPSHOT/springloaded-1.2.2.BUILD-SNAPSHOT 。罐
为了在 grails 下测试它，我要做的是进入 grails 文件夹：grails-2.5.0/lib/org.springframework/springloaded/jars
然后我重命名那里的弹簧罐，并在上面的罐子中放置一个符号链接。过去，您只需修改 startGrails 脚本以指向新版本，但现在由于分叉，我发现您需要执行符号链接。或者将该 jar 放入此文件夹并重命名以符合 grails 的期望（将其从 springloaded-1.2.2.BUILD-SNAPSHOT.jar 重命名为 springloaded-1.2.0.RELEASE.jar）
If you want to rollback instead
如果你想回滚
Grails is natively supported in 1.8.0_25, 1.8.0_31
1.8.0_25、1.8.0_31 原生支持 Grails
Once you have a compatible java version clean your grails project. Ensure that your java path variables are set to point to your expected version.
一旦你有一个兼容的 java 版本，清理你的 grails 项目。确保您的 java 路径变量设置为指向您的预期版本。

I updated my springloaded jar to version 1.2.4.BUILD-SNAPSHOT (from 1.2.1) and that resolved the issue. (Latest version can be found in the Spring repo)
我将 springloaded jar 更新到版本 1.2.4.BUILD-SNAPSHOT（从 1.2.1 开始）并解决了问题。（最新版本可以在Spring repo 中找到）
- Go to your local Grails lib directory to find springloaded jar. For me that was
/usr/local/Cellar/grails/2.4.4/libexec/lib/org.springframework/springloaded/jars/ - remove existing 1.2.1 jars (I removed pom file, too, but not necessary)
- download latest springloaded jar and place into the
jarssubdir:wget http://repo.spring.io/libs-snapshot-local/org/springframework/springloaded/1.2.4.BUILD-SNAPSHOT/springloaded-1.2.4.BUILD-SNAPSHOT.jar
- 转到您本地的 Grails lib 目录以查找 springloaded jar。对我来说那是
/usr/local/Cellar/grails/2.4.4/libexec/lib/org.springframework/springloaded/jars/ - 删除现有的 1.2.1 jar（我也删除了 pom 文件，但不是必需的）
- 下载最新的 springloaded jar 并放入
jars子目录：wget http://repo.spring.io/libs-snapshot-local/org/springframework/springloaded/1.2.4.BUILD-SNAPSHOT/springloaded-1.2.4.BUILD-SNAPSHOT.jar
After doing that, everything works. (Clues used from previous answer: https://github.com/spring-projects/spring-loaded/issues/98)
这样做之后，一切正常。（先前答案中使用的线索：https: //github.com/spring-projects/spring-loaded/issues/98）

I thought I should add my two pence worth on this topic. Recently I hit the same issue trying to upgrade an ancient app to 2.4.4. The reason for my post is because all of the above instructions are a little out of date and whilst in most cases it may appear to work. The moment you introduce mysql drivers all of the above mentioned versions of spring loaded hit a new issue around incompatibility and Non-root when attempting to trigger the database.
我想我应该在这个话题上加上我的两便士。最近我在尝试将一个古老的应用程序升级到 2.4.4 时遇到了同样的问题。我的帖子的原因是因为上述所有说明都有些过时，而在大多数情况下，它似乎有效。当您引入 mysql 驱动程序时，所有上述版本的 spring 加载在尝试触发数据库时遇到了关于不兼容和非 root 的新问题。
I got ggts fully working with JDK 1.8_065. To make it work get hold of springloaded-1.2.5.RELEASE.jarPut this into grails-2.4.4/lib/org.springframework/springloaded/jars/folder.
When you install ggts inside the ggts-bundle folder is grails-2.4.4. So put the file in the above location within the ggts-bundle folder. Unless you have changed configuration.
Re-launch GGTS
I spent ages on it and thought I should update the instructions.
我让 ggts 与 JDK 1.8_065 完全兼容。为了让它工作得到springloaded-1.2.5.RELEASE.jar把它放到grails-2.4.4/lib/org.springframework/springloaded/jars/文件夹中。当你在 ggts-bundle 文件夹中安装 ggts 是 grails-2.4.4。因此，将文件放在 ggts-bundle 文件夹中的上述位置。除非您更改了配置。
重新启动 GGTS 我花了很长时间，并认为我应该更新说明。
Also the other thing that I hit issues around was forking under grails 2.4.4 with my uprade and ended up setting
我遇到的另一件事是在 grails 2.4.4 下用我的升级分叉并最终设置

Two Step To Make it Work
两步让它发挥作用
1. Download JDK Lower Version:Install jdk1.8.0_25 from link http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html#jdk-8u25-oth-JPR. It's the lower version of JDK as grails dont support higher version. Maybe They'll include this in latest version soon.
1.下载JDK低版本：从http://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase8-2177648.html#jdk-8u25-oth-JPR链接安装jdk1.8.0_25 。这是 JDK 的低版本，因为 grails 不支持高版本。也许他们很快就会在最新版本中包含这个。
2. Set Up Environment Variables:Don't forget to change the Enviromental variables for jdk, you have to just edit Path Variables and JavaHome Variable from "C:\Program Files\Java\jdk1.8.0_'LatestVersion'" to "C:\Program Files\Java\jdk1.8.0_25".
2.设置环境变量：不要忘记更改jdk的环境变量，您只需将Path Variables和JavaHome Variable从“C:\Program Files\Java\jdk1.8.0_'LatestVersion'”编辑为“C :\Program Files\Java\jdk1.8.0_25"。

Changing the springloaded version in my pom.xml did the trick.
在我的 pom.xml 中更改 springloaded 版本可以解决问题。
<dependency>
<groupId>org.springframework</groupId>
<artifactId>springloaded</artifactId>
<version>1.2.6.RELEASE</version>
</dependency>
When I was experiencing the issue my springloaded version was 1.2.1.RELEASE
当我遇到这个问题时，我的 springloaded 版本是 1.2.1.RELEASE
