A DESCRIPTION OF THE PROBLEM :
API specification says about create of BasicTextAreaUI :
"Returns a WrappedPlainView or PlainView". But in some cases this method returns BoxView and other views.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run (see "source code for an executable test case"):
javac CreateTest.java
java CreateTest


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
View is instance of PlainView or WrappedPainView according to documentation.
ACTUAL -
  xxxxx@xxxxx  
false
false
javax.swing.plaf.basic.BasicTextAreaUI$  xxxxx@xxxxx  
false
false


REPRODUCIBILITY :
This bug can be reproduced always.

Is this bug fixed?

I reproduced the output on WinXP with the current Java SDK version - that is without Java 6u1 update.

I think Java 6u1 update fixes some Swing bugs however i am not sure if this still needs to be fixed. 

Here is the output from my test with the Testcase mentioned above:

Type of v: javax.swing.text.BoxView@10dd1f7
PlainView false
WrappedPlainView false
Type of v:javax.swing.plaf.basic.BasicTextAreaUI$PlainParagraph@53c015
Plain View false
WrappedPlainView false

SOLUTION?

Can it be that create() returns BoxView because BoxView is parent class of WrappedPlainView? The API documentation says that WrappedPlainView is directly inherited from BoxView so i assume this is a class type issue.
