Request to backport 5082756: Image I/O plug-ins set metadata boolean attributes to "true" or "false" into OpenJDK6

[Joe Darcy]

Hi Pavel.

This topic is addressed in the process discussion on the OpenJDK 6 
project page:

"As an implementation of the Java SE 6 specification, all changes to 
OpenJDK 6 must be allowable within that specification. This requirement 
precludes many API changes. Acceptable API changes include those 
permitted by the endorsed standards mechanism, such as upgrading to a 
newer version of a standalone technology, like a component JSR. One 
example of such an API change was the upgrade of JAX-WS from 2.0 to 2.1 
in OpenJDK 6 build b06.

Changes allowable within the Java SE 6 specification may still be 
rejected for inclusion in OpenJDK 6 if the behavioral compatibility risk 
is judged as too large. Behavioral compatibility concerns implementation 
properties of the JDK. Clients of the JDK can knowingly or unknowingly 
come to rely upon implementation-specification behaviors not guaranteed 
by the specification and care should be taken to not break such 
applications needlessly. In contrast, if a change is appropriate for 
every other JDK release train, it is generally appropriate for OpenJDK 6 
too. Examples of such universal changes include security fixes and time 
zone information updates."
