Misuse Details

Details about the known misuse from the MUBench dataset.

Description:	Iterator.next() is invoked without prior check of hasNext().
Fix Description:
Violation Types:	missing/condition/value_or_state
In File:	com/google/javascript/jscomp/deps/SortedDependencies.java
In Method:	cycleToString(List)
Code with Misuse:	`class SortedDependencies { /** * @param cycle A cycle in reverse-dependency order. */ private String cycleToString(List<INPUT> cycle) { List<String> symbols = Lists.newArrayList(); for (int i = cycle.size() - 1; i >= 0; i--) { symbols.add(cycle.get(i).getProvides().iterator().next()); } symbols.add(symbols.get(0)); return Joiner.on(" -> ").join(symbols); } }`
