Braces not correctly matched in Groovy due to closures

[Mahesha999]

I have Eclipse Luna (Service Release 1a (4.4.1)) with following plugins installed:

Groovy-Eclipse Feature
Groovy Compiler 2.0 Feature 2.9.1.xx-201412191752-e44
Grails IDE 3.6.3.201411271013-RELEASE

I have a simple class:

class Utilities 
{
    public static boolean hasValue(List list){
        return !(list == null || list.isEmpty());
    }
}

Another simple class:

class Test2 {        
    static main(def args)
    {
        def var1 = [2]        
        if(Utilities.hasValue((List)var1)  //here one bracket is less but still compiler does not give any error
        {
            println "hello"               
        }
    }
}

It is only when I run Test2, it gives me following exception:

No signature of method: static Utilities.hasValue() is applicable for argument types: (java.util.ArrayList, Test2$_main_closure1)

Also when I add another if() to Test2, then it gives not much sensing error description:

class Test2 {        
    static main(def args)
    {
        def var1 = [2]        
        if(Utilities.hasValue((List)var1)  
        {
            println "hello"               
        }
        if(true) { }  //Groovy:Expecting '}', found 'if'
    }
}

I tried same in Groovy/Grails Tool Suite (which is also eclipse based) by GoPivotal v 3.3.0.RELEASE. It also gives same error.

For some reason, the compiler isn't picking up that the parenthesis are mismatched in your source (the line ... if(Utilities.hasValue(... is missing a closing paren. Without the paren, it's possible the code block for the if is being interpreted as a closure ... and the extra if throws enough additional code into the mix that syntax errors are finally recognized. Strange that it initially passed code validation (after running it, I removed the paren that I had added, and eclipse properly identified a syntax error in the code).
