Motivation:
https://github.com/netty/netty/pull/8866 added support for calling Iterator.remove() but did not add a testcase.
Modifications:
Add testcase to ensure removal works.
Result:
Better test-coverage.
Motivation:
KObjectHashMap.remove(int index) attempts to move back items which may have been displaced because their spot in the hash based array was taken by another item. If this happens the nextIndex reference in PrimitiveIterator will not be updated. At this time the PrimitiveEntry will reference the incorrect index and may result in a NPE.
Modifications:
- If KObjectHashMap.remove(int index) moves entries back then PrimitiveIterator should adjust its nextIndex
Result:
PrimitiveIterator.remove() updates its internal state to reference the new nextIndex and will not NPE.
Fixes https://github.com/netty/netty/issues/5198
Motivation:
The KObjectHashMapTest is in a directory called "io.netty.util.collection" rather than "io/netty/util/collection". This causes the generated tests to be created in the wrong directory as well.
Modifications:
Moved the file.
Result:
Fixes#4546
