jecelyin / java-syntax-highlighter Goto Github PK

What steps will reproduce the problem?
1. I attached my small project that uses SyntaxHighlighter
2. To see the problem Please run model.Main class . 
Then, choose menu 'File' 
and 'Open' menuItem to open HTML file. Must be HTML file.

What is the expected output? What do you see instead?
The exception is :

What version of the product are you using? On what operating system?
JDK 1.7u51 and Windows 7.

Please provide any additional information below.
I attached my project. 

I get a StackOverflowError caused by an unmatched single quote when parsing 
scala files with a comment style such as: /* `123' */

This can be reproduced with:

    String s = "'"; for(int x = 0; x < 2000; x++) s += '\n';
    new SyntaxHighlighterParser(new BrushScala()).parse(null, s);

Which gives the same error as:

    Pattern multiLineSingleQuotedString = Pattern.compile("'((\\\\.)|([^\\\\']))*'", Pattern.DOTALL);
    String s = "'"; for(int x = 0; x < 2000; x++) s += '1';
    multiLineSingleQuotedString.matcher(s).find();

Running on OpenJDK 1.7.0_40 and ideone https://ideone.com/AnAJdf

This seems to be fixed by using a possessive quantifier in RegExpRule.java:

    public static final Pattern multiLineSingleQuotedString = Pattern.compile("'((\\\\.)|([^\\\\']))*+'", Pattern.DOTALL);

Some of the other rules here could have the same problem.
