[1.21.x] Fix Eclipse generic inference failure in testframework

[Shadows-of-Fire]

A new usage of var in DeferredBlocks.java makes ECJ fail to compile the file, due to a generic inference failure in the type of the be variable that causes the signature of func.apply to be invalid (it resolves to a wildcard instead of E).

This change explicitly types be to resolve the inference failure.
