Building bnd fails from a fresh checkout

[njbartlett]

Building from a fresh checkout of bnd fails as follows:

[javac] /Users/neil/Projects/bnd/biz.aQute.runtime/src/aQute/junit/runtime/BasicTestReport.java:26: cannot access java.lang.StringBuilder
[javac] class file for java.lang.StringBuilder not found
[javac]             System.out.println(test + " : ");
[javac]                                     ^

BUILD FAILED
/Users/neil/Projects/bnd/build.xml:5: The following error occurred while executing this line:
/Users/neil/Projects/bnd/cnf/build.xml:34: The following error occurred while executing this line:
/Users/neil/Projects/bnd/cnf/build.xml:52: Compile failed; see the compiler error output for details.

Seems the compilation classpath may not be configured correctly?
