Description

Caused by: java.lang.NullPointerException:
at org.apache.myfaces.view.facelets.tag.TagAttributeImpl.getBoolean(TagAttributeImpl.java:138)

return type is a primitive, so we can't return null.

https://github.com/apache/myfaces/blob/89c747e85615e3f33265e664c8361789f38ea7db/impl/src/main/java/org/apache/myfaces/view/facelets/tag/TagAttributeImpl.java#L138

We should check for null and, if so, return false.

Discovered TCK Test "test-faces40-selectManyCheckbox"
