[BUG] Katalon Studio 8.0.0 java.lang.ClassFormatError

@Rakeshreddy.donthire try removing <projectdir>/.cache folder. In this folder stored the compiled class files of your custom keywords. The error indicates that a class file in the folder is in bad format: perhaps the file is there but has 0-bytes. I don’t know why. By removing the .cache folder, you can let Katalon Studio to build the keyword class cleanly.
