• Git Pull Request: https://github.com/liferay-frontend/liferay-portal/pull/1138

Steps to reproduce:

1. Start a 7.3.10-dxp-1 bundle 
2.  Use curl to simulate an option request (install curl and on a separate console use the following command while the portal is running):

curl -X OPTIONS "http://localhost:8080/o/js_resolve_modules?modules=frontend-js-alert-support-web%401.0.7%2Findex"

1. Check the portal console

Expected behavior:

There won't be any errors in the log

Actual behavior:

java.lang.StringIndexOutOfBoundsException: String index out of range: -8 is thrown

 

Notes: The Baidu search engine sends OPTION requests to the servers before accessing urls, this issue can fill up the logs quite easily eventho the error itself is harmless
