Unable to parse these lines with GC promotion and reference GC information

When I opened a logfile, I got the below warnings:

It appears like the issue is with the promotion failure marker "--" appearing in them. When I edited out those markers from these lines, it was happy.

Hmm, not very nice of the logger to separate the type name and the promotion failure ;-).

I have still found a fix to this issue.

Thank you, will give it a try.

I noticed that the GC-Type is extracted as "GC--", is this intentional? It would be better to show it as "GC" and capture a separate stat for number of promotion failures.

Hi Hari,

I just realised that I forgot to answer here - I am sorry!

It is intentional, that the type extracted is "GC--", because the
promotion failure is part of that GC. You get separate stats for events
with and without promotion failures ("GC--" are those with promotion
failure, all others not).
