IBM HeapAnalyzer wont open

I downloaded IBM Support Assistance Workbench, Installed HeapAnalyzer 4.5.4. When I try and start the HeapAnalyzer tool I get this error:

Cannot Launch HeapAnalyzer - Could not find the main class: com.ibm.jinwoo.heap.HeapAnalyzer

I cannot seem to launch HeapAnalyzer

Could not find the main class: com.ibm.jinwoo.heap.HeapAnalyzer. Program will exit.

Has anyone else experienced this and know how to fix it?

Solution

  • type java --version does the version agree with 51.0

    you may need to install the latest jdk, or you can export the JAVA_HOME for the IBM JDK and add $JAVA_HOME/bin to your path
