Description

Bad Groovy

def myMap = [:] as Map<String, Map<String,String>>
def foo = ''

tells:

Error

1 compilation error:

expecting EOF, found 'def' at line: 2, column: 1

but:

Good Groovy

def myMap = [:] as Map<String, Map<String,String> >
def bar = ''

works fine.

Difference lies between >> and > > (with space).

Fix "Bad Groovy" assignment.
