How do I get unit test to run in java 7: java.lang.VerifyError: Expecting a stackmap frame at branch target

Question

Hi I am running a maven test using maven 3.0.3 with hibernate 4.0.0 Final release and spring 3.1 on jdk7 update 2.

I get the following error.

Caused by: java.lang.VerifyError: Expecting a stackmap frame at branch target 63 in method ${myDomainClass}.equals(Ljava/lang/Object;)Z at offset 24

My Equals method is using EqualsBuilder from commons-lang 2.6. I set the following maven opts

SET MAVEN_OPTS=%MAVEN_OPTS% -XX:-UseSplitVerifier

after reading this Java 7 JVM verifyError

Note: My test works under jdk 1.6 update 29.

How do I fix this? It seems setting -XX:-UseSplitVerifier still causes the error.

Answer 1

According to surefire plugin documentation MAVEN_OPTS are not inherited by a spawned JVM, so you need to specify argLine config parameter with -XX:-UseSplitVerifier in maven-surefire-plugin configuration element.

Answer 2

You appear to be running afoul of the "improved" bytecode verifier (which is actually dumbed-down such that it demands a lot more verifier info be supplied by the compiler). You need to either get your code processed by a compiler string that produces the "improved" bytecode format or else have the version of the class file set to the "old" version (which I'm thinking would be something less than 50.0).
