Checkstyle formatting.
Build docs (1 remaining lengthy line).
Clarified the multiple addIndex and setPrimaryKey methods.
Restored previous COUNTER increment scheme.

- Source code formatting (Eclipse will find this)
- Missing Javadoc class comment
- The test didn't compare myString (Eclipse will find this)
- Missing space around '=' (Checkstyle will find this)

- Javadoc comment for the class was missing (./build.sh should find this)
- Make fields private where possible
- Do not comment source code (// EventLogger.activateConsoleLogger();). Remove it.
- Simplify error code assertions

- Typos in Javadocs (./build.sh spellcheck finds this)
- Use private fields where possible
- Fix Javadoc with something that isn't a sentence
- Fix Javadoc without an actual comment
- The workaround 'clazz' instead of 'class' is not needed for 'dateClazz'
- Javadoc for parameters is inconsistent / incorrect
- Javadoc: undocumented return
- Javadoc comments are usually lowercase except for sentences

- Fix bug about using an (unordered) set for index and primary key columns
- Non-private fields first (Checkstyle reports this)
- Comments are on a separate line (Checkstyle)
- Space before and after "=" (Eclipse reports this)
- Comment, specially comment fragements, are lowercase

- Let it compile with JDK 5

- Make fields and methods private where possible
- Add missing Javadocs
- Remove @throws Javadocs (all other languages don't have throws, and it doesn't help much documenting them)
- Use camel case for metaData
- Remove initializing to default values (null, 0, false) because that's anyway done automatically
- Remove @Override to let it compile with JDK 5
- Mark as 'work in progress'

- Add class level Javadoc documentation (I hope it's somewhat correct)
- Make fields private if possible
- Enable the trace option when running in standalone mode
- Instead of System.out.println(), use trace()
- Remove 'verbose' flag, use the trace flag instead
- Remove @Override so it can be compiled with JDK 5 (so that the nightly build works)
- Use { .. } even for single line blocks - this is the code convention used in H2 (so that insertion of a new line of code anywhere is always "safe")

- Improve Javadoc documentation
- Javadoc: add missing documentation for <T> (the IDE or checkstyle flags this) 
- Javadoc: removed trailing whitespace
- Remove @Override tag because this won't compile with JDK 5
- Flag that there is something wrong (what if 'y' isn't a Number? anyway instanceof should be avoided)

- Improve Javadoc documentation
- Javadoc: removed unpaired <p>
- Javadoc: removed shouting (bold, caps "MUST")
- Javadoc: document parameters
- Javadoc: no need to write Return in a @return tag
- Javadoc: make correct sentences, not sentence fragments ('Default Db Upgrader.' is not a sentence)
- Remove @Override tag because this won't compile with JDK 5
- Methods in public interfaces don't need to be declared public (Checkstyle detects this, please use Checkstyle as documented)

- Improve Javadoc documentation
- Add Javadoc documentation (each class and interface method should be documented)
- I didn't want to use MessageFormat but I guess that's not an important change

- add missing //## Java 1.5 end ##
- according to checkstyle final static fields names are all caps
- remove trailing spaces (please configure the IDE accordingly)
- add missing space after comma (please configure checkstyle)

Please note that counter++ is counter.getAndIncrement() and not counter.incrementAndGet(). But I guess this doesn't make a difference here.

MVCC: the probability of lock timeouts is now lower if multiple threads try to update the same rows.

Linked tables / MS SQL Server: if the tables were created in mixed case in MS SQL Server, then the identifiers in the linked tables were case sensitive (in H2).

H2 Console: opening a MS SQL Server database is now faster. Also, listing the database meta data sometimes resulted in an exception.

MVCC: the probability of lock timeouts is now lower if multiple threads try to update the same rows.

Some people reported NullPointerException in FileObjectDiskMapped. The most likely explanation is that multiple threads access the same object at the same time. Therefore, the public methods in this class are now synchronized.

Building only the documentation (without compiling all classes) didn't work, specially: ./build.sh clean javadocImpl.

The pseudo-column "_ROWID_" now supports insert, update, and merge (only enabled for version 1.3.x).
