          public void setPerformClearTagStateForTagPoolingServers(boolean performClearTagStateForTagPoolingServers)

      Description copied from class: `StrutsBodyTagSupport`
      Request that the tag state be cleared during `StrutsBodyTagSupport.doEndTag()` processing, which may help with certain edge cases with tag logic running on servers that implement JSP Tag Pooling. Note: Even though the Tag classes extend this class `StrutsBodyTagSupport`, and this method `StrutsBodyTagSupport.setPerformClearTagStateForTagPoolingServers(boolean)` exists in the method hierarchy, the JSP processing requires us to explicitly override it in every Tag class in order for the Tag handler method to be visible to the JSP processing. Defining a setter in the superclass alone is insufficient (results in "Cannot find a setter method for the attribute").

      See `StrutsBodyTagSupport.clearTagStateForTagPoolingServers()` for additional details. Warning: Setting this value to true may allow for the desired behaviour, but doing so may violate the JSP specification. Set to true at your own risk.

      Overrides:
        `setPerformClearTagStateForTagPoolingServers` in class `AbstractUITag`
      Parameters:
        `performClearTagStateForTagPoolingServers` - true if tag state should be cleared, false otherwise.
