Java Snippet runs once then keeps failing until KNIME app is restarted

Hi @takbb, yes, the exception message looks similar to mine, but as the code in this Java snippet node is able to run without any errors when I restart Knime, I can’t understand why it starts failing after I open and close the configuration dialogue box to simply add or remove a line break, which should make no difference to the Java compiler.

My guess is that something happens to the system settings and/or the runtime environment at this point, which can only be corrected by a complete restart of the Knime application.
