Description

In previous versions of Grails before JsonSlurper was significantly changed, this test passed. However, it fails in Groovy 2.3.x (tested up to 2.3.3).

void testParseNumWithDecimals() {
   def i = parser.parseText('123.40')
   BigDecimal i2 = 123.40G
   assert i instanceof BigDecimal
   assert i == i2
}

This test should be added to https://github.com/groovy/groovy-core/blob/GROOVY_2_3_X/subprojects/groovy-json/src/test/groovy/groovy/json/JsonSlurperTest.groovy

In Groovy 2.3.3, the assertion fails as i = 123.4G, not 123.40G.
