What steps will reproduce the problem? 1. Download and extract the current distribution [GCLogViewer-0.3-win.zip] on a Windows 64 bit system ( x86_64) 2. Navigate to the extracted folder and execute the run.bat file

What is the expected output? What do you see instead? Expected Output -> The SWT UI should be launched Instead the following error message is displayed

C:\GCLogViewer-0.3-win>java -Djava.ext.dirs=. -Xms512M -Xmx512M code.google.gclogviewer.GCLogViewer Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot load 32-bit SWT libraries on 64-bit JVM at org.eclipse.swt.internal.Library.loadLibrary(Library.java:177) at org.eclipse.swt.internal.Library.loadLibrary(Library.java:151) at org.eclipse.swt.internal.C.<clinit>(C.java:21) at org.eclipse.swt.widgets.Display.<clinit>(Display.java:130) at code.google.gclogviewer.GCLogViewer.main(GCLogViewer.java:78)

What version of the product are you using? On what operating system? GCLogViewer-0.3-win.zip Windows 7 64 bit

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

Hi team,

Still we couldn't open a verbose gc log file using 64-bit version of gclogviewer. When we try to open we got the below listed exceptions
