Stats.java

From Line 203 to Line 207

  String s = r.readLine();
    while (s != null)
    {
        add(s);
    }

如果java 参数中没有加上 -XX:+PrintGCTimeStamps 在GCLogAnalyze.java 
第97行

double happenTime=Double.parseDouble(line.substring(0,line.indexOf(":")));

会出现parseDouble转换的问题。

Please provide any additional information below.

I was able to resolve the issue faced by replacing the 32 bit SWT jar files 
packaged within the distribution
Remove - 
org.eclipse.swt.win32.win32.x86_3.4.1.v3449c.jar
org.eclipse.swt_3.4.1.v3449c.jar
swtgraphics2d.jar

Download the 64 bit SWT libraries from 
http://archive.eclipse.org/eclipse/downloads/drops/R-3.6.1-201009090800/download
.php?dropFile=swt-3.6.1-win32-win32-x86_64.zip & place the following files in 
the original location where the GCLogViewer was extracted. 

swt.jar 
swt-debug.jar

What steps will reproduce the problem?
1. 使用CMSGC，系统运行一段时间后观察gclogviewer
