in repository https://gitbox.apache.org/repos/asf/tinkerpop.git
commit 7c9964381344279bda2dd82086bc4422ab7f613b
Author: Stephen Mallette <stepm...@amazon.com>
AuthorDate: Tue Feb 13 09:24:40 2024 -0500
TINKERPOP-3056 Fixed bug in mid-traversal mergeE for onMatch
Since the current traverser was only being updated onMatch when it was used
as a start step doing mutations in a sideEffect() would update whatever the
current traverser was. This code may have been leftover from a time when the
merge steps operated more readily on the current traverser as an argument to
the step.

* Fixed issue where server errors weren't being properly parsed when sending
bytecode over HTTP.
* Improved bulkset contains check for elements if all elements in bulkset are
of the same type
* Fixed bug in `EarlyLimitStrategy` which was too aggressive when promoting
`limit()` before `map()`.
+* Fixed bug in mid-traversal `mergeE()` where mutations in `sideEffect()` were
being applied to the current traverser rather than a `onMatch` edge.
