Description

The following test case fails with Groovy version 1.5.6.

NEWLINE = System.getProperty("line.separator")

void doTest(def param) {
	try {
		StringWriter sw1 = new StringWriter()
		StringWriter sw2 = new StringWriter()
		StringWriter sw3 = new StringWriter()

		sw1.write(String.valueOf(param))
		sw2.print(String.valueOf(param))
		new PrintWriter(sw3).print(param)

		assert sw1.toString() == sw2.toString()
		assert sw1.toString() == sw3.toString()

		sw1 = new StringWriter()
		sw2 = new StringWriter()
		sw3 = new StringWriter()

		sw1.write(String.valueOf(param))
		sw1.write(NEWLINE)
		sw2.println(param)
		new PrintWriter(sw3).println(param)

		assert sw1.toString() == sw2.toString()
		assert sw1.toString() == sw3.toString()
	}
	catch (AssertionError e) {
		System.err.println(param)

		throw e
	}
}

doTest(null)
doTest("foo")
doTest(true)
doTest(false)
doTest((byte)123)
doTest((short)1234)
doTest(new Integer(1234))
doTest(new Long(9999999999))
doTest(new Float(1234.5678))
doTest(new Double(1234.5678))
doTest(new BigInteger("123456789012345678901234567890"))
doTest(new BigDecimal("12345678901234567890.1234567890123456789"))
doTest(new Date())
doTest(new StringBuffer("bar"))
doTest([null, "foo", true, false, new Integer(1234)])
doTest(["foo" : "bar", "true": true, "int": new Integer(1234)])
