[GROOVY-8099] An error about "org.codehaus.groovy.syntax.SyntaxException: Access to java.lang.Object#pOfferingInstId is forbidden"

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.4.5

Description

1.We use static compilation and AST conversion to compile scripts.
The original expression is:
def bunledSubOfferInstReq = deepClone()
The converted expression:
def bunledSubOfferInstReq = (pkg.ViewObject) pkg.FunctionRuntimeTool.invokeFunction(this, deepClone)

2.The class pkg.ViewObject is implement java.util.Map interface.

3.When using the ViewObject property in BinaryExpression, it is wrong to put it in an if statement.

--compile successed
def bunledSubOfferInstReq = deepClone()
bunledSubOfferInstReq.pOfferingInstId = bunledSubOfferInstReq.pOfferingInstId

--compile failed
if (condition)
{
def bunledSubOfferInstReq = deepClone()
bunledSubOfferInstReq.pOfferingInstId = bunledSubOfferInstReq.pOfferingInstId
}

4.I found a phenomenon cause this error, at compile successed situation, the ClassNode of ViewObject has redirect. [toString result-pkg.ViewObject -> pkg.ViewObject]
At comile failed situation, the ClassNode of ViewObject redirect is null. [toString result-pkg.ViewObject]

5.The error stacktrace as below:
org.codehaus.groovy.syntax.SyntaxException: Access to java.lang.Object#pOfferingInstId is forbidden @ line 106, column 43.
