When using Arquillian 1.0.0.Alpha5 or SNAPSHOT versions on a Sun JDK version 1.5, the following error occurs:

java.lang.UnsupportedClassVersionError: Bad version number in .class file

(stack trace below)

The error occurs on the first line in this getType() method:

InjectionPointImpl.class

------------------------

@Override

public Type getType()

{

ParameterizedType type = (ParameterizedType) field.getGenericType();

if(type.getActualTypeArguments()[0] instanceof ParameterizedType)

{ ParameterizedType first = (ParameterizedType)type.getActualTypeArguments()[0]; return (Class<?>)first.getRawType(); }

else

{ return (Class<?>)type.getActualTypeArguments()[0]; }

}

It only occurs when the instance producer is for an ArquillianDescriptor which extends a newly used

Descriptor from ShrinkWrap. It appears that ShrinkWrap was compiled only for Java 1.6.

The field being injected is this one:

private org.jboss.arquillian.spi.core.InstanceProducer org.jboss.arquillian.impl.bootstrap.ConfigurationRegistrar.descriptorInst

The templated type is this descriptor:

org.jboss.arquillian.impl.configuration.api.ArquillianDescriptor extends org.jboss.shrinkwrap.descriptor.api.Descriptor

...and these are the header infos from the corresponding classes:

// Compiled from Descriptor.java (version 1.6 : 50.0, no super bit)

public abstract interface org.jboss.shrinkwrap.descriptor.api.Descriptor {

// Compiled from ArquillianDescriptor.java (version 1.5 : 49.0, no super bit)

public abstract interface org.jboss.arquillian.impl.configuration.api.ArquillianDescriptor extends org.jboss.shrinkwrap.descriptor.api.Descriptor {

The ArquillianDescriptor was probably compiled with Java 1.6, but set to target version 1.5

The full stack trace is as follows:
