XLS reader execution error

Hello everybody,

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
this message:
“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.

Hi Marty,

this seems to be a bug, can you send us an example file? As I could not reproduce this behavior?

Cheers, Iris
