1. I got the following error: java.lang.UnsupportedClassVersionError: com/ibm/jinwoo/performance/linux/Application (Unsupported major.minor version 49.0). What should I do?
The tool requires Java Run-time Environment 5.0 or above. If your default Java Run-time Environment is not 5.0 or above, please use the -vm option, which allows the tool to find Java Run-time Environment. For example, try jpal -vm c:\java5\bin\java.exe if your Java 5.0 executable is at c:\java5\bin\java.exe.
2. The tool told me that no Java virtual machine was found. What should I do?
Follow the steps in question 1, above.
3. Java heap space got exhausted. What should I do?
If you get Java heap exhaustion due to large trace, please use the -vmargs -Xmx option in order to increase the Java heap. For example, jpal -vmargs -Xmx1024m will allocate 1 GB of Java heap to the tool environment.
