Problem Description: A Java class with methods such as "is()" and "contains()" that is instantiated by CF via createObject does not make such methods available.

Steps to Reproduce:

Example 1 (Java Object)

{code:java}
<cfscript>
gate = createObject( "java", "com.braintreegateway.BraintreeGateway" ).init(env,merchant.getMerchantAccountId(), merchant.getMerchantAccountPublicSecret(),merchant.getMerchantAccountPrivateSecret());
req = createObject( "java","com.braintreegateway.CustomerSearchRequest").id().is("#user.getUserId()#");
customer = gate.customer().search(req);
</cfscript>
{code}

Error Thrown: Invalid CFML construct ... ColdFusion was looking at the following text: is

Example 2 (CFC)

<!--- Junk.cfc --->

{code:java}
<cfcomponent>
    <cffunction name="is">
        <cfreturn true>
    </cffunction>
    <cffunction name="contains">
        <cfreturn true>
    </cffunction>
</cfcomponent>
{code}


<!--- test.cfm --->

{code:java}
<cfset o = new Junk()>

<cfoutput>
    #o.is()#<br />
    #o.contains()#<br />
</cfoutput>
{code}

This - predictably - outputs:

true
true
However we have problems if we introduce a init() method to Junk.cfc, thus:


{code:java}
<cffunction name="init">
    <cfreturn this>
</cffunction>
{code}

And then adjust test.cfm accordingly:


{code:java}
#o.init().is()#<br />
#o.init().contains()#<br />
{code}


Actual Result:  Compiler error... Invalid CFML construct found on line x at column xx.

ColdFusion was looking at the following text:

is

[...]

coldfusion.compiler.ParseException: Invalid CFML construct found on line 4 at column 19.

at coldfusion.compiler.cfml40.generateParseException(cfml40.java:12135)
[etc]

There is no valid reason why o.init().is() should not be OK if o.is() is fine.

Expected Result:

Any Workarounds: None known

Yeah, this should "just work". -- Adam

required for braintree integration

This is a much needed fix.

This is an edge case where parser breaks while parsing a method chain where one of the function name is one of the ColdFusion special keys like is, contains, EQ etc. Making required changes in the parser at this moment would be bit risky.

"At this moment"? You've had the issue in front of you for a year and a half: how come you're only getting around to looking at it *now*, when you're pushed for time? -- Adam

bugs like this should be fixed promptly and it's hardly an edge case, it's a serious issue.

Need to add support for method chain where one of the function name is one of the ColdFusion special keys like is, contains, EQ etc.

Verified, this still exists in ColdFusion 10. needed for braintree payments integration

Verified, this still exists in ColdFusion 2016. needed for braintree payments integration
