Java 7 JVM VerifyError in Eclipse

问题

When I compile my project in eclipse indigo using JDK 7, I get the following error dialog

with the following stacktrace

Exception in thread "main" java.lang.VerifyError: Expecting a stackmap frame at branch target 32 in method ... at offset 0
    at java.lang.Class.getDeclaredMethods0(Native Method)
    at java.lang.Class.privateGetDeclaredMethods(Unknown Source)
    at java.lang.Class.getMethod0(Unknown Source)
    at java.lang.Class.getMethod(Unknown Source)
    at sun.launcher.LauncherHelper.getMainMethod(Unknown Source)
    at sun.launcher.LauncherHelper.checkAndLoadMain(Unknown Source)

I've found a relevant bug here and used the suggested workaround of using jvm option -XX:-UseSplitVerifier and although it works, this bug still confuses me.

Does anyone know why this is happening and why the workaround...works?

--Note--

The project compiles fine using JDK 6.

回答1:

Bug 353467 speaks about "using -XX:-UseSplitVerifier to activate the old verifier".
That is consistent with the JDK TM 6 Adoption Guide which describes that option as:

Traditional verifier can be forced with the -XX:-UseSplitVerifier flag.

Missing or incorrect StackMapTable attributes for version 50.0 class files can result in VerifyError exceptions.
Tools that rewrite bytecode in version 50.0 class files and do not correctly update the StackMapTable may fail to verify and trigger exceptions.

So the comment from 2011-10-03 does point out that:

AspectJ now auto activates the previously optional setting to create stackmaps if the classes are Java7.

When I had this problem, I fixed it by deleting my JDK 1.7 system libraries from the project, and added the 1.6 JDK libraries instead. I went to run the project again, and I didn't get the error. When I added the JDK 1.7 libraries in again, it still works, so something in the 'swapping' makes it work.

I hit this problem in Juno, but resolved it by installing the latest 4.2 version from the 4.2 update site here:

http://www.eclipse.org/ajdt/downloads/

That's the same one @VonC gave a year ago -- but since the updated AspectJ is there now (but not in the latest Juno repository nor with what is shipped with Spring), it now constitutes an answer.

But credit to @VonC.

Note that this should work for 3.8 as well as 4.2.

currently, my environments is jdk 1.7(j2sdk 1.7 update 21) with eclipse 4.2 juno (SR2) I had same problem, so I had fixed it which configured VM arguments Option '-XX:-UseSplitVerifier' but it has ocurred big trouble when I will deploy product based on google-app-engine.

finally I changed java 6 (update 43)
