• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 1.1-rc-3

• Component/s: class generator
• Assignee: Alex Tkachman

Description

The following code:

[code]
class DefaultNoArgCtor {
DefaultNoArgCtor(String s) {}

// DefaultNoArgCtor(int s) {} <== uncomment this line to get the BUG
}

def a = new DefaultNoArgCtor()
println a
[/code]

If you uncomment the 2nd constructor, then instead of getting an exception about not being able to find the ctor (or something similar)
what I am getting (trunk) is:
