hi Guillaume, hi Everyone, first: thanks for making Groovy! It simply is great!
I am using groovy.sql.Sql with a commons dbcp2 BasicDataSource and am encountering a stacktrace as in [2] below. I do create many identical closures with different data, and I pass them all at once to ExecutorService.invokeAll. The closures are all using the same Sql instance. I believe this is a race condition because it happens only when the database is over a network, and not when the database is local. To work around I can set Sql.cacheNamedQueries = false. Problem is reliably gone in this case. So I guess the culprit is in [1], with my sql already being cached in namedParamSqlCache, but not yet in namedParamIndexPropCache?
