Description
Below I've pasted the top part of a G1 GC log which causes a parsing error. When this happens, GCViewer seems to be completely unable to parse the rest of the file.
The problem seems to be the "Total time for which application threads were stopped" lines. If I remove these, it parses OK. With them, I get an UnknownGcTypeException on every line from 14 on.
I haven't tried to debug this yet, but will do so when I have some time.
