Strange parsing issue concerning G1 collector · Issue #128 · chewiebug/GCViewer · GitHub

Hi,

First of all, it would be great if gcviewer could ignore the "G1Ergonomics" messages from the -XX:+PrintAdaptiveSizePolicy setting.

Second, I do have a strange bug while parsing gc log files.

This one works fine :

But, this one doesn't work :

I couldn't see any structural difference between these two samples.
Here are the error messages:

Any clue ?
