shift/reduce conflict in cup parser - parsing

I wrote this grammar:
/* Precedences */
precedence left UMINUS;
precedence left ID;
Expr ::= ID:e
| NUM:e
| Expr:e1 TIMES Expr:e2
| LP Expr:e RP
;
Call ::= ID:id LP ExprComma:args RP ;
When I try to run the parser on this program:
weirdAverage(5)
(the tokens are: id lp num(which is expr) rp)
I get:
Syntax error in line 1 '('
So, I try to remove this:
precedence left ID;
And now I get an error:
[java] Warning : *** Shift/Reduce conflict found in state #16
[java] between Expr ::= ID (*)
[java] and Call ::= ID (*) LP ExprComma RP
[java] under symbol LP
[java] Resolved in favor of shifting.
[java] Warning : *** Shift/Reduce conflict found in state #79
[java] between Expr ::= ID (*)
[java] and Call ::= ID (*) LP ExprComma RP
[java] under symbol LP
[java] Resolved in favor of shifting.
[java] Error : *** More conflicts encountered than expected -- parser generation aborted

File input = new File("${pdfDir}")
pd = PDDocument.load(input) // System can't execute this line
pdfUtil.writePDF(pd, addr, data)

Dependency: compile 'org.apache.pdfbox:pdfbox:1.8.11'
As discussed in the comments: the file is empty. This is usually the reason when getting an exception like this
IOException: Error: End-of-File, expected line
with parseHeader in the stack trace.

Jenkins failure build: Internal Error: Unhandled kpi type with performance plugin

I'm running Jenkins with the Performance Plugin.
I have a multiple JMeter jmx scripts which run on jenkins and I'm trying to add this one. But the build is always failing. With this message
Internal Error: Unhandled kpi type: <type 'long'>
bzt installation is also done.
I can't seem to find much info about this on google. Any help?
After the shutdown I'm getting this:

LL(1) Parse table for S → a | ba | c

I'm new to LL(1) parsing and am currently trying to figure out how to create a parse table for the language:
S → Saa|b
and
S-> A|B
A-> aa
B-> bb
and
S → AB
A → aa
B → bb
I'll show you the complete procedure for the first grammar. Tell me if there are any aspects you would like to examine in greater depth.
S → Saa | b
1. Eliminate left recursion
S → bS'
S' → aaS' | ε
2. Left factor
No need for this grammar.
3. Compute FIRST and FOLLOW and check if the grammar is LL(1)
------------------------------------
| A → α | FIRST(α) | FOLLOW(A) |
------------------------------------
| S → bS' | a | $ |
------------------------------------
| S' → aaS' | a | $ |
------------------------------------
| S' → ε | ε | $ |
------------------------------------
4. Build the parsing table
for each prodution A → α
for each a ∈ FIRST(α)
add production A → α to M[A,a]
if ε ∈ FIRST(α) then
for each b ∈ FOLLOW(A)
add A → α to M[A,b]
Result:
-------------------------------------
| | a | b | $ |
-------------------------------------
| S | | S → bS' | |
-------------------------------------
| S' | S → aaS' | | S' → ε |
-------------------------------------
The grammar is LL(1). Here the results of the other grammars.
1.
-------------------------------------
| | a | b | $ |
-------------------------------------
| S | S → A | S → B | |
-------------------------------------
| A | A → aa | | |
-------------------------------------
| B | | B → bb | |
-------------------------------------
2.
-------------------------------------
| | a | b | $ |
-------------------------------------
| S | S → AB | | |
-------------------------------------
| A | A → aa | | |
-------------------------------------
| B | | B → bb | |

Upgrade Orbeon 3.9 to 4.5

We are upgrading Orbeon 3.9 to 4.5.
And we are using MySQL 6.1 and JBOSS 5.1.
Followed the procedures described in http://wiki.orbeon.com/forms/doc/developer-guide/form-runner/oracle-and-mysql-persistence-layers?pli=1 for upgrade.
I am getting the Form Runner Home just fine (showing the old applications and forms).
And also If I open any new form(which I created after upgrade) from form runner, its perfect, no problem.
But When I try to click on any old form , I am getting error "An error has occurred in Orbeon Forms"
And In Orbeon.log file, I can see the following :

Error while building an xtext project with ant: Generation of the Grammar classes fails

I am developing an xtext plug-in project for an eclipse application for my Bachelor thesis.
I want to do the 'Generate Xtext Artifacts' at runtime with an ant script executing the Mwe2Launcher class and do the generation in an temp folder.
I wrote an Activator to create in the temp folder a project folder and copy the mwe2 file, my grammar file and the ant script.
Executing the Ant script leads to this error:

[java] 13246 INFO Workflow - Done. BUILD SUCCESSFUL Total time: 27 seconds
The ".java" file which are unmapped were also not generated. The whole "/src-gen/...../foobar/foo" folder is missing.
I guess this is the reason and what should be fixed.
I really don't know, where the problem is. I already had a discussion in an Eclipse forum there you can find the build.xml but for another project, also an Activator class to activate the plugin and do the copy stuff and execute the ant script, also you find the mwe2 file I use.
You have to make sure that your register your temp folder as platform URI in your workflow. Xtext uses the platform:/resource URI scheme of EMF. Therefore, the platform root has to be registered in order to define the path mappings from absolute locations on the filesystem to logical locations according the the platform path. You could try to copy the .project file, too. I assume that will help if you already register the temp folder as platform path.
