Bug ID: 57316
Summary: JspC fails if directory name contains URL encoded
characters
Product: Tomcat 7
Version: 7.0.55
Hardware: Macintosh
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org
Reporter: a...@varju.ca
I ran into an issue today where my Jenkins build failed because the working
directory contained '%2F' in the name. When the build got as far as attempting
to precompile the JSPs, an exception was thrown complaining that the directory
didn't exist.
Gradle error output:
Internal Error: File /WEB-INF/web.xml not found
[ant:jasper] java.lang.NullPointerException

I believe the problem is caused by JspC.initClassLoader's call to
JspCompilationContext.getRealPath. This calls JspCServletContext.getRealPath,
which in turn uses the value from URL.getFile to build the path. This returns
a URL encoded variant of the path, which in my case means a double-encoded
path. I believe JspCompilationContext.getRealPath should be URL decoding the
return value.
