Expected BEGIN_OBJECT but was BEGIN_ARRAY from Composer plugin

[jpospychala]

I'm getting an exception in the log which says that json file begins with array instead with object. Indeed, that file begins with array, not object, but is it a bug in composer, or Gson?

Below is log with exception and futher below is composer file. It's from a ZF2-based project.

@jpospychala can you confirm if this is still happening in the latest version? i'm not indexing anymore using the lucene based indexer, but parsing solely installed.json and installed_dev.json to get the project information.

ok it seems not happening anymore
