Not actually a bug, seems like issue with version information in Online Index.
A lot of internal libraries show mismatched version numbers.
Some show ahead of online version and some lag behind (while being internal) and some do not show any online version information.
This is a list of some of them which have a mismatch in B4J:
jcontrolfx
jcontrolfx9
jfx
jgameviewhelper
jnetwork
jokhttputils2
jrandomaccessfile
jserver
jshell
jstringutils
jwebsocketclient
pybridge
simplemediamanager
