NumberFormatException: For input string: "188744K->13345K(4063232K)."

Hi.
It seems to be an unsupported GClog format found.

java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.6) (rhel-1.25.1.10.6.0.1.el5_8-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)
JVM parameters
-verbose:gc -XX:+PrintTenuringDistribution -XX:+PrintGCDetails -XX:+PrintGCTimeStamps

Exception rased here
AbstractDataReaderSun.java

protected void parsePause(GCEvent event, String line, ParsePosition pos)

246         event.setPause(Double.parseDouble(line.substring(pos.getIndex(), end).replace(',', '.')));

Code line substring(pos.getIndex(), end).replace(',', '.')) returns "188744K->13345K(4063232K)." but I think "0.0285820" is expected.

Hi,

Hmm, this looks like some mixture of Suns JDK 1.4 and 1.5 output for
-XX:+PrintTenuringDistribution. I have pushed a fix to github, please
test with the latest SNAPSHOT release
(https://github.com/chewiebug/GCViewer/wiki/Changelog).

Regards, Jörg

Works fine without any exceptions.
I can see young/tenured graphs now.
Thanks a lot!

Thank you for testing! Happy analysing :-)
