# Part 1: Lexer: Improve handling of grammars using a lexer with backtracking Entering: ``` var x = "Test"<Enter> ``` into a java platform shell yields exceptions. Checking the java lexer showed, that the java lexer at that point does backtracking and this indicates a problem in the lexer infrastructure. The problem seems to be caused by the generic lexer infrastructure, which has special handling for languages embedded into other languages. In the case of the jshell lexer, this is java code inside the shells code. In combination with a backtracking lexer this seems to break lexing. # Part 2: Improve handling of `var` Statement - parser falsely reports that var is not supported - parser reports missing semikolon The first condition needs to be newly caught, the second condition was partially caught in `SemicolonMissingRule`, but failed because there is an potential off-by-one issue. -- This is an automated message from the Apache Git Service.
