dependancy on 1.5.0 tools

[Al Sutton]

I've just been looking through the core pom.xml in HEAD and noticed this;

        <profile>
            <id>default-tools.jar</id>
            <activation>
                <property>
                    <name>java.vendor</name>
                    <value>Sun Microsystems Inc.</value>
                </property>
            </activation>
            <dependencies>
                <dependency>
                    <groupId>com.sun</groupId>
                    <artifactId>tools</artifactId>
                    <version>1.5.0</version>
                    <scope>system</scope>
                    <systemPath>${java.home}/../lib/tools.jar</systemPath>
                </dependency>
            </dependencies>
        </profile>

Sun have announced 1.5 is now in it's end of life transition period (see 
http://java.sun.com/javase/downloads/index_jdk5.jsp), so should we bump this to 
6.0, or if we don't actually need tools.jar maybe remove it?
