java / lang / NoClassDefFoundError：java / lang / invoke / MethodHandle eclipse juno

Question

Im running Eclipse Juno on Mac OSX 10.8.4, I tried to update my jdk to 1.7 when I run my Java App and I have this error:

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/invoke/MethodHandle

if I run on terminal

java -version

I get this

java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)

for updating this I set on Eclipse

Window - Preferences - Java - Installed JREs - Duplicate

JRE home: /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
JRE name: Java SE 7 (MacOS X Default)

also changed compiler level

Window - Preferences - Java - Compiler - Compiler compilance level: 1.7

also added next lines to /Users/myUser/.bash_profile:

VA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home

export JAVA_HOME=$VA_HOME
export CLASSPATH=$VA_HOME
export PATH=$PATH:$JAVA_HOME/bin

but still getting same error

Any help I'll appreciate

Answer 1

在启动配置中，检查正确的JRE系统库是否在Classpath上

Answer 2

Have you added JAVA_HOME to your PATH? Usually you get this problem due to a bad installation of the SDK. Try

javac -version

From the command line and see if this differs to

java -version

And produces the same NoClassDefFoundError as above.

Answer 3

The most probable reason of java/lang/NoClassDefFoundError is that you have a jar in your classpath which references another jar which is missing in classpath. The referencing classes won't be initialized.

Now for your case, you upgraded to 1.7 which would have added dependencies. Make sure your classpath now refers to jdk/jre 1.7
