ICloud Notes app is logging lots of errors deny file-write-create externalrecordsworkfiles et al

Question

I am getting intermittent error in the log, when using Notes in iCloud storage. When the errors come, they come in large batches.
Like this, many of them (dozens in one note-writing session)
2/11/13 1:04:17.525 PM sandboxd[1097]: ([363]) Notes(363) deny file-write-create /Library/Caches/com.apple.coredata.externalrecordsworkfiles
And fewer of these:
2/11/13 1:00:52.000 PM kernel[0]: Sandbox: sandboxd(1097) deny mach-lookup com.apple.coresymbolicationd
And one of these:
2/11/13 12:52:47.130 PM sandboxd[1090]: ([1091]) mdworker(1091) deny file-write-owner /Users/xxxxxxxx/Library/Containers/com.apple.Notes/Data/Library/Notes/NotesV1.s toredata-wal (import fstype:hfs fsflag:480D100 flags:240000005F diag:0 uti:com.apple.notes.externalrecord plugin:/Library/Spotlight/Notes.mdimporter - find suspect file using: sudo mdutil -t 5593589)
It is clear to me Notes is having problems. I've seen this when using Notes since upgrading to 10.8, but also after upgrade to 10.8.2 recently (MBPro 2011 13", SRAM disk).  I go typing away in toes but I see the Console icone bouncing in the dock while I'm working. 
I'll run disk-verify-fix but I'm not seeing a lot of relevant entries, just this so far:
Verifying permissions for “Macintosh HD”
Group differs on “Library/Java”; should be 0; group is 80.
Permissions differ on “Library/Java”; should be drwxr-xr-x ; they are drwxrwxr-x .
Permissions differ on “System/Library/Frameworks/CoreGraphics.framework/CoreGraphics”; should be lrwxrwxrwx ; they are lrwxr-xr-x .
Permissions differ on “System/Library/Frameworks/CoreGraphics.framework/Resources”; should be lrwxrwxrwx ; they are lrwxr-xr-x .
Permissions differ on “System/Library/Frameworks/CoreGraphics.framework/Versions/Current”; should be lrwxrwxrwx ; they are lrwxr-xr-x .
- all permissions now fixed.

When you say using the JDK you mean just using a simple text editor and command line to compile?
I'm not too bothered about decompilation as I doubt anyone would go though the effort to decompile this particular program. As it currently stands I'm the only one known in my college class to try my hand at Java anyway. Anyone else handing a java project in would be very suspicious.
How big would the program be if the JVM was included? Is it an intricate process to combine the two?
I am aware that any code can be decompiled but e.g. VB programs can only be decompiled into assembly... atleast I have yet to see a proper VB decompiler in action.
The app.path Java equivelant I need so the files needed by the program which should be in the same directory can be found with ease.
What compiler did JBuilder come with? It's own or did they simply include Sun's?
Whats the general opinion of V J++? is it pretty much Java or has M$ screwed it over and turned it into their own?
When an argument is passed to a method in Java is it referenced in memory or is a copy created? How do I pass an array to a method? and not create a copy of it? ref?
Can applets perform read and write actions on the machine it is stored? Can I refuse connections if a client is already connected?
Thanx
