Description

GCtoolkit does not support simple logs. That is, logs where each GC event is described on a single line. Such log, for example, can be generated, when using Parallel GC with unified logging and minimal arguments.
Example vm args: -XX:+UseParallelGC -Xlog:gc:file=gc.log
Example log: gc_parallel.log

Why this is important:
These minimal-configuration logs sometimes are the first logs users produce when diagnosing GC behavior, before they move on to more advanced logging options.

Research direction

Start with the attached gc_parallel.log and compare its single-line GC events with the log formats GCtoolkit currently supports. Trace the existing parsing path for GC events, then verify that the sample log is parsed successfully and that its events produce the expected toolkit output.
