We have a GWT app deployed to tomcat (7_59) and fairly often when we send a bunch of request quickly we're seeing undefined methods in the logs - and the calls fail, causing issues with our app. We make calls via RestyGwt (latest version) but GwtRequests all show this - both though after a number of REST calls in a short period of time. So for example...
[ip-addr] - - [20/Feb/2015:15:24:34 -0500] "DELETE /path1 HTTP/1.1" 200 304 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "DELETE /path2 HTTP/1.1" 200 310 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "DELETE /path3 HTTP/1.1" 200 307 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "undefinedDELETE /path4 HTTP/1.1" 501 304 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "DELETE /path5 HTTP/1.1" 200 304 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "DELETE /path6 HTTP/1.1" 200 310 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "DELETE /path7 HTTP/1.1" 200 307 [ip-addr] - - [20/Feb/2015:15:24:34 -0500] "undefinedDELETE /path8 HTTP/1.1" 501 304 Similarly... ... .... "undefinedPOST /gwtRequest HTTP/1.1" 501 1136 Very little info online, but did come across this old bug... https://bz.apache.org/bugzilla/show_bug.cgi?id=49779 In fiddler, the headers are identical between the requests that work and those that fail. Resending the failed request completes normally. So far we've only be able to reproduce this when using Internet Explorer (10 & 11) and we've spent a lot of time trying to figure out what's going on - but have been unable. Any pointers/explanations? Thanks!
