I am using Optaplanner 6.0.0-Beta2 and I am in some cases receiving the
following error during initial solution construction:
Exception in thread "main" java.lang.RuntimeException: Unexpected global

I noticed this error in gist:
https://gist.github.com/ge0ffrey/5236604
If this is the same error, what are the current constraints that I need
adhere to in order to avoid this error?

I presume you're building your own KieBase and setting it with
setKieBase() ?
If so, that KieBase is empty or corrupted or something, but it doesn't
fail-fast either apparently.
Look at this code for inspiration (that's where I ran into it too):
https://github.com/droolsjbpm/optaplanner/blob/master/optaplanner-core/sr...
Please let us know what exactly the problem was here on the mailing list.
I want to create a jira for DROOLS to fail-fast during KieBase
construction when a misconfiguration happens.

My problem turned out to be due to a lack of understanding of what
KieFileSystem does.
I'm still not sure i fully understand but I noticed that you added a fixed
prefix to your path provided to kieFileSystem.write(...)
I didn't have this prefix and used the provided path directly. When this
path was absolute or did not fall under what KieFileSystem obviously
prefers, i would get the Unexpected global [scoreHolder] error once
planning started.
From what I can tell, this error occurred anytime the provided path
began
with something other than src/main/resources/

It seems to also throw this error any time the path includes the character: \
Even properly escaped in the string as \\

Which path in what file?

I am calling KieFileSystem.write(String path ,String content) but the same
issue may be experienced with any of the versions of write that take a
"path" parameter but I haven't tried them.
I found that if the path parameter includes a character \ there is no error
produced when calling KieFileSystem.write(...).
When a KieBuilder.buildAll() is called a warning is logged:
[o.d.compiler.kie.builder.impl.AbstractKieModule ] No files found for
KieBase defaultKieBase
Then when solving begins the exception is thrown:
java.lang.RuntimeException: Unexpected global [scoreHolder]
(the same stack trace provided at the beginning of this thread).
For my code I've done a String regex just before the write call to swap any
\ into /
replaceAll("\\\\","/")

Looks like a bug in drools, not really relate to optaplanner as it
happens before you set this KieBase on OptaPlanner's SolverFactory, I
presume?
If (and only if) it reproduces with drools 6.0.0.Final (optaplanner
6.0.0.Final uses that version), create a new jira:
https://issues.jboss.org/browse/DROOLS
We're in squashing bugs mode, so it's a perfect time to create these
jira's :)

The exception is not finally thrown until the call to
solver.solve();

then file a jira in optaplanner, it might be optaplanner's fault in
ScoreDirectorFactoryConfig.java.
