Java Mustang 将会包含和可能会包含的部分 JSR：
Each of the large new components of the Mustang release is specified in
its own separate JSR. Smaller additions and changes will be specified in
the concurrent JCP maintenance review of the platform specification. All
features, JSRs and otherwise, are described in more detail below, but for ease of reference the component JSRs are
enumerated here along with their JCP status at the time of writing.
XML Digital-Signature APIs
Streaming API for XML (StAX)
Web-Services Metadata
Java Compiler API
Java Class-File Specification Update
JDBC 4.0
Java Architecture for XML Binding (JAXB) 2.0
Scripting for the Java Platform
Java API for XML-Based Web Services (JAX-WS) 2.0
Common Annotations
Pluggable Annotation-Processing API
The original submission of this umbrella
JSR mentioned three potential component JSRs that will not, as it turns
out, be part of Mustang.
JSR 260, the Javadoc Tag Update,
will not be included because the JSR 260 Expert Group was unable to
reach consensus on a number of critical issues in time for the Mustang
release. JSR 268, the Java Smart-Card I/O
API, will not be included because the JSR 270 Expert Group concluded
that it would not be of sufficiently wide interest in the Mustang time
frame. The “JAXP.next” JSR will not be included because it was
never submitted. Minor changes to the JAXP 1.3 API will be handled
in a maintenance review of JSR 206.
