When I tried to execute an XLS reader node,
I got this error message:
“Execute failed: (“executionInInitializerError”): null”
When I press the execute button again, I got
“Execute failed: could not initialize class org.knime.core.data.util.memory.memoryAlertSystem”
Before today, I had no problem executing xls
reader nodes, those errors only happened today.
Can anyone help please? Thanks.
