Mageia 2021-0072: tomcat security update

When serving resources from a network location using the NTFS file system it was possible to bypass security constraints and/or view the source code for JSPs in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances
