Friendly Jira Robot created ERT-433: --------------------------------------- Summary: Invalid octal escape sequence (\8) causes IllegalArgumentException [EBZ#501790] Key: ERT-433 URL: https://issues.jboss.org/browse/ERT-433 Project: Eclipse Release Train Issue Type: Task Components: JSDT Reporter: Friendly Jira Robot Priority: Critical Created attachment 264269 Stack Trace Any file containing a string with '\8' or '\9' in it will cause an IllegalArgumentException whenever ASTParser executes on it. This prevents the JavaScript editor from being initialized, preventing normal opening of the file. '\#' in pre ES5 is used to denote an octal escape sequence, and so \8 and \9 are indeed invalid, but this should be reported as an error in the file. The error is thrown in org.eclipse.wst.jsdt.core.util.JsStringScanner#scanEscape() and is not caught. To reproduce: create a new JavaScript file, add the line `var x = "\8"` to it, and attempt to save the file. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
