JDK 8 code review request for 7007535: (reflect) Please generalize Constructor and Method
by joe.darcy＠oracle.com 29 Feb '12

29 Feb '12

Hello. Please code review my JDK 8 changes for 7007535: (reflect) Please generalize Constructor and Method http://cr.openjdk.java.net/~darcy/7007535.3 To summarize the changes, a new superclass is defined to capture the common functionality of java.lang.reflect.Method and java.lang.reflect.Constructor. That superclass is named "Executable" along the lines of javax.lang.model.ExecutableElement, which models constructors and methods in the JSR 269 language model. Both specification and implementation code are shared. To preserve the right @since behavior, it is common that in Method/Constructor the javadoc for a method will now look like: /** * {@inheritDoc} * @since 1.5 */ Since Executable is being created in JDK 8, it would be incorrect for methods in that class to have an @since of 1.5; adding the @since in Method/Constructor preserves the right information. It would have been natural to also move common fields to Executable; however, HotSpot treats the Constructor and Method type specially and relies on the existing field ordering. Since altering the field layout would require coordinated HotSpot changes, I'm opting to not perform such a change right now. At least one abstract accessor method is declared in Executable to still allow code sharing even though the required field is not present. In other cases, package private instance methods on Executable are passed the needed state from overridden public methods in Method/Constructor. All java/lang/reflect regression tests pass on a full build with these changes. Thanks, -Joe

java.util.UUID.fromString performance
by Vitaly Davidovich 29 Feb '12

Hi all, I noticed that this method could be made a bit more performant by: 1) creating a statically initialized Pattern for "-" and then calling split() on that. Currently the method calls name.split() which compiles the pattern on each invocation. 2) use Long.parseLong() instead of Long.decode() to extract the bits. With these changes, the method runs at least 20% faster (some runs were significantly faster) on an Intel Westmere server and should be a bit more GC friendly. Any thoughts? I can send the full code a bit later when I'm in front of my computer. Thanks Sent from my phone
