getting syntax error from nifi ExecuteScript processor inspite of correct python code

I am getting below error inspite of correct python code don't know how to resolve this error. Any help is much appreciated
org.apache.nifi.processor.exception.ProcessException: javax.script.ScriptException: SyntaxError: no viable alternative at input '*' in <script> at line number 35 at column number 26
python code
def get_match_list(regEx, line):
match = re.search(regEx, line)
print(match)
if match:
match_list = [*match.groups()] # this is the line exception is pointed
return match_list
else:
return []

It looks like jython use python 2.7 and as Unpacking Generalizations is a feature that introduced in python 3.5 you can not use this syntax in jython, so an alternative way to convert a tuple to a list is that use list ( match.groups) it works fine in older versions of python and current version of jython (2.7.2)

Problems generating '.pas' file with Java2OP and compiling it

I have 2 JAR files coming from an SDK that I have to use.
Generation problem
I succeeded in generating the first .pas file, but Java2OP fails to generate the second .pas I need, with the message
Access violation at address 0042AF4A dans the 'Java2OP.exe' module. Read at address 09D00000
Would this come from a common issue? There's no other hints about what causes the problem in the SDK .jar.
I'm using Java2OP located in C:\Program Files (x86)\Embarcadero\Studio\18.0\bin\converters\java2op, but I had to first use the solutions in Delphi 10.1 Berlin - Java2OP: class or interface expected before generating the 1st file.
Compilation problem
Anyway, I tried to generate a .hpp file from the generated .pas.
I don't know much about Delphi. Does the problem come from the SDK itself, or the generation of the .pas file?
1st issue solved
Java2OP included Androidapi.JNI.Java.Util
and not Androidapi.JNI.JavaUtil. I had to import Androidapi.JNI.JavaUtil myself, though it is present in the /Program Files(x86)/Embarcadero/... folders.
2nd issue
The same 4 compilation errors happen multiple times across the .pas file on parts using the word this.
Do I have to replace every use of this with self?

OSB fn:bea Function using XQuery Engine in Java

After some research I haven't found a solution, but quite alot of people with this problem:
I am trying to do a XQuery Transformation in a Java Application using
net.sf.saxon.s9api
However I get this error when trying to compile XQueryExecutable exec = compiler.compile(...)); my XQuery:
Error on line 13 column 3 of AivPumaRequest.xquery:
XPST0081 XQuery static error near #... fn-bea:inlinedXML(fn:concat#:
Prefix fn-bea has not been declared
Error on line 44 column 102 of AivPumaRequest.xquery:
XPST0081 XQuery static error near #... div xdt:dayTimeDuration('P1D'#:
Prefix xdt has not been declared
Error on line 199 column 3 of AivPumaRequest.xquery:
XPST0081 XQuery static error near #... fn-bea:inlinedXML(fn:concat#:
Prefix fn-bea has not been declared
Error on line 282 column 4 of AivPumaRequest.xquery:
XPST0081 XQuery static error near #... {fn-bea:inlinedXML(fn:concat#:
Prefix fn-bea has not been declared
net.sf.saxon.s9api.SaxonApiException: Prefix fn-bea has not been declared
Is there a way to static include this prefix or what am I missing so my XQuery Engine (SAXON) finds the Prefix?

The simple answer to your question is that you can declare namespace prefixes either within the query prolog using
declare namespace fn-bea = "http://some-appropriate-uri";
or in the Saxon API using
XQueryCompiler.declareNamespace("fn-bea", "http://some-appropriate-uri")
But this won't get you any further unless (a) you know what URI to bind the prefixes to, and (b) you make the functions with these names available to the query processor.
The reference to xdt:dayTimeDuration suggests to me that this query was written when XQuery was still a working draft. If you look at the 2005 working draft, for example
https://www.w3.org/TR/2005/CR-xquery-20051103/
you'll see in section 2 that it uses a built-in prefix
xdt = http://www.w3.org/2005/xpath-datatypes
By the time XQuery 1.0 became a recommendation, the dayTimeDuration data type had been moved into the standard XML Schema (xs) namespace, so you can probably simply replace "xdt" by "xs" - though you should be aware that the semantics of the language probably changed in minor details as well.
As for fn-bea:inlinedXML, the choice of prefix suggests to me that this was probably a built-in vendor extension in the BEA query processor, which was taken over by Oracle. The spec here:
https://docs.oracle.com/cd/E13162_01/odsi/docs10gr3/xquery/extensions.html
says:
fn-bea:inlinedXML Parses textual XML and returns an instance of the
XQuery 1.0 Data Model.
Which suggests that the function does something very similar to the XQuery 3.0 function fn:parse-xml(), and I suggest you try making that replacement in your query.

Why doesn't printStackTrace work in Clojure?

In both the Joy of Clojure and on Alex Miller's Pure Danger Tech blog-post it is recommended that you can print the last stack using something like the following:
(use 'clojure.stacktrace)
(java.util.Date. "foo")
(.printStackTrace *e 5)
But I can't get any of their examples to work, and instead just get
java.lang.NullPointerException: null
Reflector.java:26 clojure.lang.Reflector.invokeInstanceMethod
(Unknown Source) jtown$eval9755.invoke
What's up with this? .printStackTrace seems to be a Java function from the looks of it, so I am not sure why I am bringing clojure.stacktrace into my namespace, in the first place. I read through the clojure.stacktrace API, though, and see an e function, which seems similar too but is not the *e function, which is in core and is supposed to be binding to the last exception, but isn't. Could somebody straighten me out on the best way to check stack-traces?

There are some special vars available when using the REPL and
*e - holds the result of the last exception.
For instance:
core=> (java.util.Date. "foo")
IllegalArgumentException java.util.Date.parse (Date.java:615)
core=> (class *e)
java.lang.IllegalArgumentException
core=> (.printStackTrace *e)
java.lang.IllegalArgumentException
at java.util.Date.parse(Date.java:615)
<not included.....>
You are right, .printStackTrace is the java method that is invoked on the exception class. This is not very straightforward (since its java interop) so clojure.stacktrace namespace has some utilities about working with stack traces
So after
(use 'clojure.stacktrace)
you can use the stacktrace library instead of java interop:
core=> (print-stack-trace *e)
java.lang.IllegalArgumentException: null
at java.util.Date.parse (Date.java:615)
<not included.....>
Obviously in an app, instead of *e, you can do a try - catch and use the related functions as necessary

I use
(.printStackTrace *e *out*)
That seems to work.

error 1200 mismatched input 'as' expecting SEMI_COLON when using DayExtractor in Pig

I'm trying to follow this tutorial to analyze Apache access log files using Pig:
http://venkatarun-n.blogspot.com/2013/01/analyzing-apache-logs-with-pig.html
And i'm stuck with this Pig script:
grpd = GROUP logs BY DayExtractor(dt) as day;
When i execute that in grunt terminal, i get the following error:
ERROR 1200: mismatched input 'as' expecting
SEMI_COLON Failed to parse: mismatched input 'as'
expecting SEMI_COLON
Function DayExtractor is defined from piggybank.jar in this manner:
DEFINE DayExtractor
org.apache.pig.piggybank.evaluation.util.apachelogparser.DateExtractor('yyyy-MM-dd');
Ideas anyone?
I've been searching for awhile about this. Any help would be greatly be appreciated.

I am not sure how the author of the blog post got it to work, but as far as I know, you cannot use as in GROUP BY in pig. Also, I don't think you cannot use UDFs in GROUP BY. May be the author had a different version of pig that supported such operations. To get the same effect, you can split it into two steps:
logs_day = FOREACH logs GENERATE ....., DayExtractor(dt) as day;
grpd = GROUP logs_day BY day;
