Checked signatures and checksums

Checked building from source with the following tasks:
install installGroovy dist testAll
with one test failure[*]

Rat[**] found one 3-line test file without a header:
subprojects/parser-antlr4/src/test/resources/core/LocalVariableDeclaration_02x.groovy

I did some preliminary testing of native lambdas using this test example:
```
@ groovy.transform.CompileStatic
def method() {
//[1, 2, 3].collect(e -> e.plus 1)// Ex1: JDK 7 & 8
[1, 2, 3].stream().map(e -> e + 1).toList() // Ex2: JDK 8
}
println method()
```
The examples above worked fine and appeared to produce the correct bytecode.
However, when using "e.plus 1" in my Ex2, I got:

java.lang.NoSuchMethodError:
java.lang.Number.plus(Ljava/lang/Number;)Ljava/lang/Number;
I wasn't sure if this was expected or not. I am unsure whether this is
expected behavior but even
if not, I don't see this as necessarily important enough to hold up an
alpha release.
Numerous examples do work as I expected and we'll get much more feedback
with the release out.

* MemoizeAtMostTest#testMemoizeAtMostConcurrently failed which, although
possibly deserves
  further investigation, has been fixed since the release was cut with a
change in the test which
  would have passed. It doesn't impact prod code so I believe shouldn't
hold up the release.

** Our quality build skips the parser-antlr4 directory when checking since
it isn't a real project.
We should fix this but it can wait until after this release.

GROOVY-5306 (?= operator)

[eric.milles]

GROOVY-5306 (https://issues.apache.org/jira/browse/GROOVY-5306) states:

Add "a ?= 2" support: should be expanded to "a = a == null ? 2 : a"

Shouldn't the expansion be "a = (a != null ? a : 2)"?  Like other ternary 
situations, the alternative would not be evaluated unless needed.  Also, is it 
a null check and not Groovy truth in the condition?

If "a" is not null in this example, does the bytecode actually execute an 
assignment?  That seems unnecessary as well.

Guillaume,

Don't overdo it, and get well soon.
