What’s new
-
GC Log Analyzer now parses and displays Recompilation Scanner statistics from GC logs. The Recompilation Scanner periodically inspects compiled methods and enqueues recovery recompiles for those running below their intended optimization level. These statistics are recorded in GC logs from Zing 26.08.0.0. The new data is listed in the section Recompilation Scanner, which contains the following charts:
-
Scans - The number of scan cycles completed.
-
Methods Inspected (Per Scan) - The number of compiled methods visited in each scan.
-
Recompilation Activity (Per Scan) - Includes Candidates (capped methods detected running below their intended optimization level, still active), Enqueued (recovery recompiles enqueued), and Skipped Recovery (candidates rejected by the recovery callback, for example due to OSR, a compiler directive, tier, or having already been recovered).
-
Scan Total Times - The cumulative wall-clock time spent scanning.

The GCLA Log Summary page now correctly displays the profile download status for both HTTP and gRPC-based transfers, including cases where the JVM falls back from one mode to the other. Previously, when the download occurred via HTTP as a single request rather than the expected gRPC chunk-based transfer, GCLA incorrectly reported an error even though the profile was successfully downloaded.
For profiles downloaded over HTTP, the summary now also reports transfer details, including the number of bytes received, the download duration and rate, the compression ratio, and the processing time.
