Description

Derby raises an error during byte-code generation when asked to invoke a routine declared to have a NUMERIC argument and to be bound to a method with a BigDecimal argument. According to the ANSI standard (see DERBY-3652), SQL NUMERIC is supposed to map to Java BigDecimal. This is the experiment I ran:

1) I built the 10.4 source, including the AnsiSignatures class (I will attach this).

2) I ran a script which declared a function with a NUMERIC argument bound to a method in AnsiSignatures which has a BigDecimal argument.

3) When I invoked the function, the byte-code generator raised an exception.

I am not sure what we want to happen here. The BigDecimal class does exist in Foundation Profile 1.1.2. For small device platforms which support FP 1.1.2, it seems reasonable that NUMERIC should map to BigDecimal as the ANSI spec requires. For small device platforms which don't have a BigDecimal class, I don't know what we should do. In any event, the current behavior seems wrong. Here's what I see:
