Mustang、Dolpin更名JDK6、JDK7

其中 Mustang将自带数据库javaDB


来自TSS上的消息:
David Van Couvering has written that "Java DB is bundled in Mustang," meaning that users who use Java 6 will have a full relational database as part of the JDK (not, it should be noted, the JRE).

However, one has to ask: why JavaDB, instead of the much smaller HSQLDB or One$DB? Considering that derby.jar is 2MB (not including the tools and network client code, which adds another half meg) is it worth it? Is Derby's implementation of SQL - basically a Java port of DB2, for all intents and purposes - the "right one?" Would you rather have seen a more Oracle-like implementation, or perhaps nothing at all?
