Add parameter

[feifeiniu-se]

https://github.com/apache/commons-configuration/commit/92bf8ccdad173f1f5d4a506043d443fd0cac09a6, in this commit, I didn't see any Add Parameter refactoring, but change parameter "NamingEnumeration enum" into "Context parentContext", the original method declaration didn't exist "private recursiveGetKeys(keys List) : void".

@feifeiniu-se Methods recursiveGetKeys() and getStartingContextPoint() declare a variable named enum, which is a reserved keyword since Java 1.5

So, the parser fails to parse the body of these methods.

The way to overcome this is to set the parser with Java 1.4 compatibility

Map<String, String> options = JavaCore.getOptions();
options.put(JavaCore.COMPILER_CODEGEN_TARGET_PLATFORM, JavaCore.VERSION_1_4);
options.put(JavaCore.COMPILER_SOURCE, JavaCore.VERSION_1_4);
options.put(JavaCore.COMPILER_COMPLIANCE, JavaCore.VERSION_1_4);
parser.setCompilerOptions(options);

However, checking whether the file contains a variable named enum has a computation cost, and thus I don't want to implement this check.

This is the diff of the methods. It is clear that parameter NamingEnumeration enum becomes a local variable (Localize Parameter refactoring) and Context parentContext is an added parameter.

The same parameter Context parentContext is also added in method getStartingContextPoint()
