JAPI Harmony/JDK5 Report - http://www.kaffe.org/~stuart/japi/htmlout/h-jdk15-harmony.html#pkg_java_lang

J2SE 1.4.2

Current code in classlib is assumed compliant with J2SE 1.4.2 specification.

Java 5.0

There is some support for new Java 5 APIs and enhancements. Below are some details about what's available, missing and in process.

java.lang

Primitive Wrapper Updates

There were only minor updates to the primitive wrapper classes for Java 5. The biggest addition is the 'valueOf' method to each class, which is generally used by compilers to facilitate boxing.

• Boolean (API: done, Test Case: done), references: http://issues.apache.org/jira/browse/HARMONY-179
• Byte (API: done, Test Case: done), references: http://issues.apache.org/jira/browse/HARMONY-180
• Short (API: done, Test Case: done), references: https://issues.apache.org/jira/browse/HARMONY-201
• Integer (API: done, Test Case: done), references: http://issues.apache.org/jira/browse/HARMONY-210
• Long (API: done, Test Case: done), references: http://issues.apache.org/jira/browse/HARMONY-214
• Float (API: done, Test Case: partial-done), references: http://issues.apache.org/jira/browse/HARMONY-239
• Double (API: done, Test Case: partial-done), references: http://issues.apache.org/jira/browse/HARMONY-244
• Character (API: partially complete, Test Case: partially complete)
  • https://issues.apache.org/jira/browse/HARMONY-197 - Added basic code point support.
  • Character.UnicodeBlock - Update complete; matches Java 5 specification.
  • Unicode 4.0.0 (4.0.1?) support in process
  • https://issues.apache.org/jira/browse/HARMONY-1418 - upgrade to 5.0.
  • https://issues.apache.org/jira/browse/HARMONY-1436 - upgrade to 5.0.
    
    

All primitive wrapper objects have been uplifted to include the generics signatures; references: http://issues.apache.org/jira/browse/HARMONY-355, http://issues.apache.org/jira/browse/HARMONY-356, http://issues.apache.org/jira/browse/HARMONY-392.
