filter not followed by BoolParenExpression broken

[GoogleCodeExporter]

What steps will reproduce the problem?
Access a URI such as 
Products?$filter=not (Discontinued eq 1 or UnitsOnOrder le 70)
See attached QueryOptionTest.java, method 
SystemQueryOptionFilterLogicalNotTest2.

What is the expected output? What do you see instead?
Expected output for the test case is a JSON result.

Instead, we get an exception.
Caused by: Exception [EclipseLink-8024] (Eclipse Persistence Services - 
2.1.2.v20101206-r8635): org.eclipse.persistence.exceptions.JPQLException
Exception Description: Syntax error parsing the query [SELECT t0 FROM Products 
t0 WHERE NOT ((t0.Discontinued = 1 OR t0.UnitsOnOrder <= 70) = TRUE)], line 1, 
column 85: syntax error at [=].

What version of the product are you using? On what operating system?
0.5 snapshot from October 26.

Please provide any additional information below.
I've attached a fix for this problem.  See JPQLGenerator.java method 
toJpql(BoolCommonExpression).
