Trap SIGINT in Gradle plugin
Check if response is committed before tryying to forward

It' sthe best we can do, but the container seems to still use our error page
(it just can't have the status code that we asked for).

Delegate shell access decision to bean named "shellAccessDecisionManager"

In order to solve issues with multiple or incompatible AccessDecisionManagers, the CRaSH integration will now only delegate to an explicit shellAccessDecisionManager bean refs #1121
Re-order shutdown hook in BootRunTask
Revert BootRunTask changes since they don't add anything

(Was an attempt to get Cygwin to recognise the interrupt, but it seems
to be doomed so not worth having the extra code in there really.)
RabbitMQ virtual hosts can how start with a slash

The autoconfig strips out slashes where necessary to make a valid
hostname

Drop JarEntryFilters from constructor and methods

Drop JarEntryFilter arguments from the JarFile constructor and the
getNestedJarFile methods. Filtered JarFiles can still be obtained by
using the getFilteredJarFile() method.

This helps simplify the code a little and will make it easier to add
caching.

See gh-1119
Reuse previously parsed entries for filtered JARs

Update JarFile to reuse the previously parsed entries when creating
filtered jars. This saves needing to re-scan the underlying file to
recreate a subset of entries.

See gh-1119
Add JarFile caching

Cache root jar files in the Handler and also store nested jar files in
the JarEntryData.

Improve performance of fat jar loading

Tweak 'fat jar' handling to generally improve performance:

- Allow JarURLConnection to throw a static FileNotFoundException when
  loading classes. This exception is thrown many times when attempting
  to load a class and is silently swallowed so there is no point in
  providing the entry name.
- Expose JarFile.getJarEntryData(AsciiBytes) and store AsciiBytes in
  the JarURLConnection. Previously AsciiBytes were created, discarded
  then created again.
- Use EMPTY_JAR_URL for the JarURLConnection super constructor. The URL
  is never actually used so we can improve performance by using a
  constant.
- Extract JarEntryName for possible caching. The jar entry name
  extracted from the URL is now contained in an inner JarEntryName
  class. This could be cached if necessary (although currently it is
  not because no perceivable performance benefit was observed)
