Work Description: JCgH4164838Gh792C124B5 opened a new pull request #489:
URL: https://github.com/apache/struts/pull/489
WW-5124 - Proposed fix for Struts JSP tag behaviour on application servers
that use tag pooling.
- Prior to this change, on application serves such as Glassfish, tag pools
that re-use tag instances demonstrated incorrect behaviour, due to previous /
old tag state still being present.
- Added new clearTagStateForTagPoolingServers() to StrutsBodyTagSupport. It
is called in doEndTag(), and descendants that override doEndTag() should call
the ancestor method or directly call clearTagStateForTagPoolingServers().
- Unit test support methods were added to StrutsInternalTestCase and
AbstractTagTest.
- Basic sanity checks for existing unit tests were added where feasible.
They reflection-compare a tag's state after doEndTag() is called with that of a
new instance, to help catch if future changes miss calls in the
clearTagStateForTagPoolingServers() hierarchy.
- Removed some unused imports, added some missing override annotations to
classes that were modified as part of this change.
