Title: Accept patches on javax.imageio and org.jcp.xml.dsig

Accept some from javax.imageio and org.jcp.xml.dsig. All applied and compiled fine.

There are a few patches that due to the removal of casts the code goes from two lines down to one. i.e from:

```
foo =
(Bar) bar;
```
down to
```
foo=bar
```
I forget what the decision was on changing the number of lines but assuming it is ok, all these patches are fine.
