RFR(S): 8187679: [MVT] VM crashes with "assert(k != __null && !(((ThreadShadow*)__the_thread__)->has_pending_exception())) failed: can resolve klass?"

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8187679
http://cr.openjdk.java.net/~thartmann/8187679/webrev.00/

With -XX:+ValueTypePassFieldsAsArgs (which is the default), we need to resolve all value type arguments when generating 
adapters for a method to collect the field types. If the klass cannot be resolved, we currently fail with an assert or 
crash in product.

If klass lookup during adapter generation fails, we should pass the exception up and exit with a ClassNotFoundException.

All tests pass.

Thanks,
Tobias
