After updating xCustomListView internal Library to 1.68 i got this error:
java.lang.UnsupportedClassVersionError: b4j/example/customlistview has been compiled by a more recent version of the Java Runtime (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0
My jdk is jdk1.8.0_202. 32 bits.
Maybe xCustomListView was compiled with java 9+?
Any chance could be recompiled with java 8?
I was running latest B4J version .. but somehow had really old versions of jFX and XUI libs in Core libs folder ?? which did not help situation.
I will retry Java update when I return from short camping trip.
Yesterday i had the same effect - i tried to use an jar file at customers place and got the error message: java.lang.UnsupportedClassVersionError. So i switched back to java8. Is it true, that all customers have to go to java11, before we change?
