Description

(Excuse for my bad English)
To reproduce try:
1) Open NetBeans
2) Goto Tools -> Open Java Platform Shell
3) On JShell window write: var
the last char (r) don't written. If you retype "r", this time is showed, but "enter key" do nothing.
I attach message.log after put this lines on netbeans.conf:
-J-Dorg.netbeans.lib.lexer.TokenList.level=FINER
-J-Dorg.netbeans.lib.lexer.inc.TokenHierarchyUpdate.level=FINEST
-J-Dorg.netbeans.lib.lexer.inc.TokenListUpdater.level=FINEST
-J-Dorg.netbeans.lib.lexer.EmbeddingOperation.level=FINER

Also I tryed on Apache NetBeans IDE Dev (Build 20180912-41067c9eb729) with same result.
