Description

class org.apache.tapestry5.internal.services.ClasspathAssetAliasManagerImpl contains method extractAssetAlias with
if (resourcePath.startsWith(pathPrefix))
{
// Prevent matching path prefix "foo" against "foobar" ... it must match against "foo/".
if (resourcePath.charAt(pathPrefix.length()) != '/')

{ continue; }

this code don't check when resourcePath.equals(pathPrefix) is true. In this case we get
Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: 20

To reproduce it just do next:

@Import(library = InternalConstants.CORE_LIBRARY)
public class Index {
}
