> Hello,
> the taglib plugin crashes with a nullpointerexception if there is a java file
> that does not have a package.
> the problem occurs if the "reader.readLine()" returns null so the trim cannot
> be executed. anyway what
> is the reason for the trim ? i just do not understand why there is a need for
> the trim.
> if you look at the code you will see that the while loop cannot work for
> classes without packages.
> because currentLine will never be null, because in the last line of the loop
> you will always get a
> nullpointer if the currentLine is expected to be null.
> i am wondering why nobody else is experiencing this bug ? maybe nobody is
> using classes without
> a package definition ;-)
> attached you will find a patch for the problem (one possible solution).
> here comes the exception :
