Using Lambda Expression with name clash results in ClassFormatError

FULL PRODUCT VERSION :
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
This issue was previously raised as JDK-8073620. That bug was closed as "Cannot Reproduce" under 8u25, 8u31, 8u40, yet the problem persists for me under 8u45. The description which follows, and the source code, remain the same as for JDK-8073620.

This is a simple Java 8 application which does the following:
- Declare a "Widget" class.
- Declare a "WidgetCollection" class that implements Iterable to contain Widgets.
- WidgetCollection overrides iterator() to support forEach().
- Populate the WidgetCollection with three Widget instances.
- Iterate through the collection, printing the names of the instances to the console.

If the iterator in WidgetCollection is instantiated using an anonymous class there is no problem. However, if the iterator is instantiated using a lambda expression which declares a local variable then a ClassFormatError occurs in the following scenario:
[1] The local variable is named after one of the locally overriden methods (i.e. "next" or "hasNext").
[2] The local variable is of type Widget.
[3] The lambda expression is actually used at runtime.
The ClassFormatError only occurs when all three of those conditions are met.

ADDITIONAL REGRESSION INFORMATION:
The problem has existed under Java 8 using 8u25, 8u31, 8u40 and 8u45.

Java releases prior to 8 are not relevant since the issue relates to a lambda expression.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
[1] Create a trivial Java application in file CreateBadClassFile.java, using the source code pasted below in the "Source code for an executable test case" section below.
[2] From the command line move to the directory containing the package 'badclassfile', and compile the code:
    javac CreateBadClassFile.java
The code should compile with any errors.
[3] From the command line run "java -version" to verify that the compiler used is "javac 1.8.0_45"
[4] Run the application from the command line, from the directory containing the package 'createbadclassfile' as follows:
    java -verbose createbadclassfile.CreateBadClassFile
[5] Verify from the verbose output that code from jre1.8.0_45 is being loaded.
[6] You will get an exception:
ClassFormatError: Duplicate field name&signature in class file createbadclassfile/WidgetCollection$1

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The expected output was a single line from System.out.println() as follows:
.foreach() call: W1 W2 W3


ACTUAL -
The actual result was a stack trace for error "java.lang.ClassFormatError: Duplicate field name&signature in class file createbadclassfile/WidgetCollection$1".

That is pasted in the "Error Message(s)/ Crash Logs" section below.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
The output from running "java -verbose createbadclassfile.CreateBadClassFile" is pasted below. Note the "ClassFormatError: Duplicate field name&signature" stack trace at the bottom of the output:

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
A simple change to one line in the source allows that output to be displayed correctly:
[1] First, note that line 16 of the source contains the declaration
private Widget hasNext = null;
That line is the cause of the ClassFormatError.
[2] The ClassFormatError occurs because the variable name "hasNext" is also the name of a method being overriden within the class.
[3] Change the name of the variable from "hasNext" to "harmless", recompile, and rerun. The application should now run without a ClassFormatError.
[4] Now change the name of the variable from "harmless" to "next" (another overriden method), recompile and rerun. The ClassFormatError returns.
[5] Also, note the size of the class file WidgetCollection$1.class. On my machine, when the ClassFormatError occurs that file is 997 bytes, yet when the code runs OK it is 1075 bytes. Changing the name of the variable is clearly having a non-trivial effect on the bytecode that gets generated.

Please email me if you cannot reproduce the problem because that implies that my instructions for reproducing the problem are inadequate. I am certain that there is an issue here that needs to be fixed.
