Research direction
Start at H3Core.java:781 and the NativeMethods.compactCells entry point, then reproduce the failure with the provided resolution-1 collection and the reported resolution-6 case. Done means compactCells handles these large polygon inputs without raising the resolution-range H3Exception.
Written by the indexing model from the issue text.
Description
We have observed that after version 3.7.0 that certain large polygons are failing the compactCells methods with the following error: `com.uber.h3core.exceptions.H3Exception: Resolution argument was outside of acceptable range
at com.uber.h3core.NativeMethods.compactCells(Native Method)
at com.uber.h3core.H3Core.compactCells(H3Core.java:781)`
We are using a resolution of 6 which produces the same error but has 1.5 million in the collection. Here is the collection Long we are sending to compactCells on resolution 1: [581487719465615359, 582222193232969727, 581193050349371391, 582613619372457983, 581927524116725759, 581584476488859647, 581241428860993535, 581289807372615679, 581681233512103935, 581729612023726079, 581434942907482111, 582169416674836479, 581483321419104255, 582217795186458623, 581188652302860287, 581923126070214655, 581580078442348543, 581237030814482431, 581285409326104575, 581676835465592831, 581725213977214975, 581087497233104895, 582165018628325375, 581478923372593151, 581184254256349183, 582604823279435775, 581918728023703551, 581575680395837439, 581232632767971327, 582015485046947839, 581672437419081727, 581720815930703871, 581426146814459903, 581083099186593791, 581474525326082047, 581179856209838079, 581571282349326335, 581228234721460223, 581716417884192767, 581078701140082687, 581470127279570943, 582204601046925311, 581566884302815231, 581223836674949119, 582006688953925631, 581663641326059519, 581712019837681663, 581025924581949439, 581074303093571583, 582200203000414207, 582248581512036351, 581219438628438015, 581659243279548415, 580973148023816191, 581707621791170559, 581461331186548735, 582244183465525247, 581215040581926911, 581654845233037311, 581311797605171199, 582389319000391679, 581017128488927231, 581945116302770175, 581650447186526207, 581307399558660095, 581698825698148351, 581012730442416127, 581452535093526527, 581940718256259071, 581646049140015103, 581303001512148991, 581694427651637247, 581008332395905023, 581448137047015423, 581201846442393599, 581936320209747967, 581593272581881855, 581641651093503999, 581298603465637887, 581690029605126143, 581003934349393919, 581443739000504319, 581100691372638207, 582178212767858687, 582226591279480831, 581197448395882495, 581931922163236863, 581588874535370751, 582323348302725119, 581637253046992895, 581294205419126783, 581685631558615039, 581734010070237183, 581439340953993215]
