SDF Reader failed: Configure failed (NoClassDefFoundError)

I am new. I want to read a SDF file. I installed http://update.knime.com/partner/4.0, so I got LigandScout installed. I drag SDF Reader to there and I entered things in Configuration. But the SDF Reader has a red cross and saying:

ERROR SDF Reader 3:1 Configure failed (IllegalAccessError): class com.inteligand.ilib.config.o (in unnamed module @0x700b7a49) cannot access class sun.font.FontManagerFactory (in module java.desktop) because module java.desktop does not export sun.font to unnamed module @0x700b7a49
