Tags: parse error addressing stored function returning bigint

In calling a stored function returning a bigint, an exception is
encountered beginning 
"java.sql.SQLException: java.lang.NumberFormatException: For input string:"
followed by text of the stored function beginning somewhere following the
argument list.   (This is pretty astonishing to see!)

The sole change of replacing the return type with 
decimal(22,0) works around the issue - but this doesn't agree with the
use of types which can be autoincremented.

How to repeat:
Run the attached test files
testFails.java    and

They are identical save for the return type change.

Exhibits failure mode

Exhibits contrasting success with workaround

There appears to be an error in parsing function return parameter type. Fetching from I__S retrieves BIGINT(20) (although I removed (20) from definition) which is discovered as BIGINT thus not in need of (m,d). But (m,d) still gets parsed throwing the error you see.

DataBaseMetaData.java 1652, TypeDescriptor returnDescriptor = new TypeDescriptor(returnsDefn, null);
returnsDefn =
    MODIFIES SQL DATA ... which is not correct.
