Hello all,
this problem has already been encoutered and seems to be related to this
bug affecting the "java.util.regex.Pattern" class:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6337993.
As a workaround, you can update your code like that:
Route route = router.attach("/result/{yourVar}", <Restlet instance or
Resource class>);
route.getTemplate().getVariables().put("yourVar", new
Variable(Variable.TYPE_ALL));
best regards,
Thierry Boileau
Hi,
I've seen a couple of other discussion about this in the past, but
didn't know if there's been any progress. Anyways, I've encountered a
java.lang.StackOverflowError when sending in a long attribute. Here's
the warning I'm getting:
Apr 8, 2008 10:59:58 AM org.restlet.util.Template match
WARNING: StackOverflowError exception encountered while matching this
string :

I'm trying to call a GET at the result resource using a list of comma
delimited uuids. When it gets to the match(String formattedString)
method and it calls getRegexPattern().match(formattedString) on the
string above, it produces a Matcher with this regex:
"/result/((?:[a-zA-Z0-9\\-\\.\\_\\~\\!\\$\\&\\'\\(\\)\\*\\+\\,\\;\\=\\:[EMAIL PROTECTED]|(?:\\%[0-9ABCDEFabcdef][0-9ABCDEFabcdef]))+)",
and I get the stack overflow when matcher.lookingAt() is called.
I've tried just matching on the above string with the regex
standalone, and it looks to be recursively calling pattern.match, and
causing the StackOverflowError.
String s =
"/result/c045d791-11b0-408e-8d60-b2f6ce6c117d,af3e28f4-2bdf-4b34-a74a-48f6c638a9b8,b242e13a-7083-45d6-a4db-5961883690db,a315b9cb-743c-422e-bb1b-bedfa93957bd,ac399b7f-5a2a-4ddc-8a7b-d1106e1e28f4,ffe736ef-5dbf-4204-a69c-b1599e012b75,1b876179-e897-4eb9-a5ae-b124fd69cbcb,b1c5abc4-b69c-4d5a-85fe-b320adab8f29,44efad37-ed0a-4bf0-80c8-55a82dfe89d3,bd43c7c4-0949-40a3-998b-b6cf0d895cc9,45b046c1-a509-4835-a801-c5bca0855d49,8260a9fd-9773-4803-8218-2de29082ef7a,2acd118a-5721-4aee-afcc-a28b3dd8bcbd,8943d432-a147-4393-afbf-5de3bbfb3f28,3db028ad-4f8c-4355-a7ca-ac4af7a712be,d00faab9-0c2d-4b5b-84bf-810e375ec38f,c8780a2a-a7be-458e-a6ef-9f73922b0ca7,16525506-0df4-453e-b930-d9fd46e08b72,a50839f2-e3b2-4604-86bf-646af2ca048d,5383406a-c566-455b-8725-2c81aba82db0,ae3ceaa9-a495-4311-8e65-4e83aa02b2ad,0cfc54f9-9852-451e-9856-a63689cbb4e3,2faaa074-b21c-4c40-a632-b5e8e84aa09a,ec4f38de-e0de-437e-9e3f-19db4576f177,185b9d55-237f-42b3-ba8a-bb005db09f2a,887ffc64-c190-439e-a9b2-261f55ea18e3,97683f00-151e-4508-8b77-5d34d1048843,1cfde617-ad79-4f81-bc30-bf017ecb5636,c4551d09-b558-40a1-96ca-eea503d72815,2fa39dc8-d375-42a6-bc11-e8cf4a91ceb8,e2198d2c-86c8-49e2-95c3-b6e88901cd68,f32600d5-1f27-4a4c-ae87-25caf0d91bdd,5156d109-aa69-4cf6-813c-7682b55d139e,b360f697-af9f-4e1e-8aff-e3d2fd510b0e,07f1db89-5b7f-4c9a-a177-003dffda8206,bc1103d2-7f0a-412e-9dc3-8c311c66c16b,2cefe92b-92ce-430f-89ee-8f2713afff2b,85cf0fb2-06d6-4d86-9146-4e8c951682b7,7acbaa77-d6bf-4271-a6b9-965ba5b83637,6ed9b90b-a533-4925-9019-282f27c32f86,4447c1b8-7333-4be1-ad37-9a552aed8243,d1e0593e-c340-4526-bc61-e98b74e2796b";

Due to this problem, we're having to hack a solution of using the POST
method for doing gets (as well as deletes) when operating on a large
batch. This works, but still a hack for what I presume to be a poorly
generated regex that's preventing us for truly using a GET to do a get
and a DELETE to do deletes. I just wanted to bring this to people's
attention, and to probe for any answers. Has there been any fix for
this, or will there be a fix for this in the future? Thanks.
