class java.lang.ClassCastException when using select parameter

[denizk]

I'm getting java.lang.ClassCastException API errors for some query.X queries that worked previously.

For example, When I interrogate the API with query string ABE, Y. [u.a.]: Increase in dicentric chromosome formation after a single CT scan in adults. Sci. Rep. (2015) 5:13882 (gutachtlich) and this request https://api.crossref.org/v1/works?rows=1&query.bibliographic=ABE%2C+Y.+%5Bu.a.%5D%3A+Increase+in+dicentric+chromosome+formation+after+a+single+CT+scan+in+adults.+Sci.+Rep.+%282015%29+5%3A13882+%28gutachtlich%29&select=DOI&select=score

produces

Some more requests that fail with the ClassCastException:

When removing the select url parameter the queries succeed. Maybe an issue with the #243 implementation?

[denizk]

The ClassCastException seems to only occur when including the score field in the select url parameter. Unfortunately, it's a field we need for downstream analysis. Is that an easy fix @kjw ?

[ale-de-vries]

I get the error as well, when trying to select alternative-id.

[denizk]

any chance to get this issue fixed?

[denizk]

@kjw not sure how the comment above unassigned you..

As long as the correct syntax is used when selecting multiple fields e.g. select=DOI,score instead of specifying the select query parameter multiple times, then this issue will be resolved by the fix for #289.
