Following Eclipse code snippet that fails:
protected void join(InternalJob job) {
final IJobChangeListener listener;
synchronized (lock) {
listener = new JobChangeAdapter() {
public void done(IJobChangeEvent event) {
barrier.release();
}
};
job.addJobChangeListener(listener);
}
}
The error reports the line containing listener = as the problem.
