decodeStructure swallows exceptions

[jschneider]

Exceptions thrown within the decodeStructure block are swallowed.

This code:

decoder.decodeStructure(descriptor) {
        TODO()
    }

throws an JsonDecodingException:
Unexpected JSON token at offset 1: Expected '}'

I assume the original exception is hidden, because the decoder tries to finish decoding the JSON object.

I strongly prefer to have the the original exception thrown.

I think the problem happens because decodeStructure always tries to finish structure in finally block:

finally {
        composite.endStructure(descriptor)
    }

AFAIR, exceptions thrown from finally block have higher priority, so the original exception is lost. And JSON decoder can't find closing brace because body hasn't been decoded, hence 'expected }'.
