Description

The description has been anonymized, but AFAIK, all important details remain.

On the following code:

Line 155: return super.<SomeClass> someMethod(someArgument);

PMD reports the following problem:

[WARNING] Error while parsing xxx\MyClass.java: Encountered " "<" "< "" at line 155, column 22.
Was expecting:
<IDENTIFIER> ...

I tried the following:
1) Updated PMD maven plugin to 2.6 (I was using 2.5)
2) Verified that the targetJdk setting is taking effect (I get an error when setting it to "xxx")
3) I set the source encoding to UTF-8 (My default is Cp1252)
4) When changing line 155 to "return (Iterable<SomeClass>) super.someMethod(someArgument);", no error is reported

So it seems that Java 5 mode is enabled, but the particular syntax of parameterizing the method call on invocation is not supported.

This is valid syntax, the code is running in production.
