[aspectj-users] NullPointerException

[NAKAGUCHI Takao <takao-n@xxxxxxxxxxxxxxx>]

I got NullPointerException when

. placing abstract aspcet(1) that has abstract pointcut and advice in jar file
. overriding abstract pointcut using the joinpoint that has cflow in the
aspect(2)

here is the part of stack trace:

  }

  public void sayHello(){
    doSayHello();
  }

  public void doSayHello(){
    System.out.println("hello.");
  }
}

-- a part of build.xml --
  <target name="compile" depends="distabstractaspect">
    <iajc
      srcdir="src"
      destDir="${build}"
      classpath="aspectjrt.jar"
      aspectPath="${dist}/abstractaspect.jar"
    />
  </target>

----

When not placing aspect(1) in jar or not using cflow in the aspect(2),
I didn't get NullPointerException.
I used JDK1.4.1_02 on Windows2000(ja) system.
