Eclipse Warning: Unsupervised Conversion and Redundant Specification of Type Arguments

I recently switched from JDK1.6 to JDK 1.7.

I have this code:

SomeClass<SomeType> someVariable = new SomeClass<SomeType>(createSomeObject());

Now I get a warning:

Redundant specification of type arguments <SomeType>

If I use a quick fix, Eclipse gives me the following:

SomeClass<SomeType> someVariable = new SomeClass<>(createSomeObject());

The result is

Got an exception - expecting EOF, found 'xyz'

xyz is the next element in the code.

When I remove the angle brackets, I get this warning:

SomeClass is a raw type. References to generic type SomeClass<M> should be parameterized

If I add a type parameter, I get the first warning (redundant specification ...)

WTF going on?

I want to keep both warnings, and I'm still using Eclipse 3.7.1. I do not want to update Eclipse if there is another way to solve this problem, since it will take me some time to configure it the way I want it again.
