UnsupportedClassVersionError
Explcitly running with java 11, but sometimes on page refresh/app launch get this. ususally if I refresh again, the error is gone. But seems quite strange, since the class in question is a Java library class. In this case it is the BasicLookAndFeel class, but sometimes it is other JRE classes:
java.lang.UnsupportedClassVersionError: Required Java version 45532, but CheerpJ only supports up to Java 11 at this time. Unsupported class: javax/swing/plaf/basic/BasicLookAndFeel

Hi, can you provide a complete example that demontrate this problem? It seems to me you are downloading corrupted data, which is not something we have ever seen before
