[jboss-jira] [JBoss JIRA] (WFLY-7398) Tab completion causes NUL characters ('\0') to be injected...sometimes

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13313402#comment-13313402 ] 

David Lloyd commented on WFLY-7398:
-----------------------------------

I'm not certain when the invalid characters actually appear.  I assume it must be after I tab, but that's really a guess (there's no visual on-screen indicator that the character is there, at least not on my terminal).

> I noticed while testing my subsystem that sometimes using tab-complete on an attribute causes NUL ('\0') characters to be injected into the input.  These characters are invisible on the screen but cause XML marshalling to fail as that character is forbidden.
> My "less" output of .jboss-cli-history looks something like this:
> {noformat}
> embed-server --std-out=echo
> cd subsystem=discovery
> ./static-provider=test:add(services=[{uri=^@^@"local", abstract-type="ejb", abstract-type-authority="jboss"}])
> ./static-provider=test4:add(services=[{uri="local", abstract-type="ejb", abstract-type-authority="jboss"}])
> {noformat}
> In the first "test:add" case I used tab-completion; in the second "test4:add" case I typed it out by hand.  The "^@" are in inverse video in less, indicating a NUL character.
