Solve the following python programming problem given the following code:
def configure_jvm(self, extra_source_paths, extra_test_paths) :

    Fix the buggy line: self.sources = self.dedup_sources (previous_set.sources)

#Here is Python code to fix the buggy line: self.

self.sources = self.dedup_sources (self.sources)
