This issue has been identified where spaces exist in the install path while opening jsp content. Upon opening log messages are produced where about illegal characters. Investigating this reveals that while the path is printed with a space, the actual string contents of the URL contains %20. This may potentially be a bug in the JSP support, however; it would be great if org.openide.util.BaseUtilities#toURI(java.io.File) recovered from this by detecting a scheme of 'file' and replacing occurrences of '%20' with a space. Steps to Reproduce ================== 1. Have the IDE in a path with a space and start. 2. Open a web project 3. Open a JSP with a taglib reference such as "<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>" Actual Behaviour ================ IDE seems to function fine (albeit am I missing functionality?), though exceptions of those attached are spat out. Desired Behaviour ================= Recover from exceptions and not litter messages.

Marking as regression as this does not appear within 8.1. As it doesn't (appear) to affect functionality am relaxing to P4.
Created attachment 160381 [details] Patch replacing dangerous File.toURL() to Utilities.toURI(File).toURL() File.toURL() [1] should be avoided as it does not escape spaces correctly, one should convert to a URI first and then to a URL.
