Description
JsonBuilder.toString() works correctly for both zero-length and longer strings. JsonBuilder.toPrettyString() incorrectly inserts a pair of escaped double-quotes into the output for zero-length strings.
Consider the following test case:
import groovy.json.* import groovy.util.GroovyTestCase class MyTest extends GroovyTestCase { void testStringZero() { def m = [ s3:'abc', s0:'' ] def json = new JsonBuilder( m ) def str = json.toString() def pretty = json.toPrettyString() def prettyTrim = pretty.replaceAll( ~/\s/, '' ) if ( false ) { println '' println 'm: ' + m println 'str: ' + str println 'pretty: ' + pretty println 'prettyTrim: ' + prettyTrim } assert str == prettyTrim } }
Enabling the prints produces:
m: [s3:abc, s0:]
str: {"s3":"abc","s0":""}
pretty: {
"s3": "abc",
"s0": "\"\""
}
prettyTrim: {"s3":"abc","s0":"\"\""}
E

There was 1 error:

assert str == prettyTrim
