Tab completion causes NUL characters ('\0') to be injected...sometimes ---------------------------------------------------------------------- Key: WFLY-7398 URL: https://issues.jboss.org/browse/WFLY-7398 Project: WildFly Issue Type: Bug Components: CLI Reporter: David Lloyd Assignee: Jean-Francois Denise Priority: Critical 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.
