[ https://issues.apache.org/jira/browse/LANG-477?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Duncan Eley updated LANG-477:
-----------------------------
Attachment: ExtendedMessageFormatTest.java
Test case
> ExtendedMessageFormat: OutOfMemory with custom format registry and a pattern containing single quotes
> -----------------------------------------------------------------------------------------------------
>
> Key: LANG-477
> URL: https://issues.apache.org/jira/browse/LANG-477
> Project: Commons Lang
> Issue Type: Bug
> Affects Versions: 2.4
> Reporter: Duncan Eley
> Attachments: ExtendedMessageFormatTest.java
>
>
> When using ExtendedMessageFormat with a custom format registry and a pattern conatining single quotes, an OutOfMemoryError will occur.
> Example that will cause error:
> private static Map<String, Object> formatRegistry = new HashMap<String, Object>();
> static {
> formatRegistry.put(DummyFormatFactory.DUMMY_FORMAT, new DummyFormatFactory());
> }
>
> public static void main(String[] args) {
> ExtendedMessageFormat mf = new ExtendedMessageFormat("it''s a {dummy} 'test'!", formatRegistry);
> String formattedPattern = mf.format(new String[] {"great"});
> System.out.println(formattedPattern);
> }
> }
> The following change starting at line 421 on the 2.4 release seems to fix the problem:
> CURRENT (Broken):
> if (escapingOn && c[start] == QUOTE) {
> return appendTo == null ? null : appendTo.append(QUOTE);
> }
> WORKING:
> if (escapingOn && c[start] == QUOTE) {
> next(pos);
> return appendTo == null ? null : appendTo.append(QUOTE);
> }
