when the content-type was not exactly 'application/x-www-form-urlencoded'
for normal POST requests, no parameter was read by the UWS/TAP library.
This content-type test has now been modified from a strict equality to a
startsWith test.
(Note: This bug only concerned the form encoded requests,
not the multipart ones)

(merge branch 'objectPosition')

(merge with branch 'unknownFctType')

in the log output. For that the function UWSToolBox.getParamsMap(...)
had to be modified.

Such value is replaced by NULL while ingesting it into a Postgres
database.

[ADQL] Fix the ADQL DEBUG mode ; now ADQLParser.setParser(boolean) is doing what it is supposed to do.

[TAP] Small fix: the translated SQL query was logged only after the query execution ; so, in case of error,
the SQL query is not logged and can not be checked by service provider.

[ADQL] Fix merge side-effects (e.g. '' were not translated any more as a single ' ; NullPointerExceptions when building positions) + transform the test main class for positions into a JUnit test case + Fix some position mistakes.
(note: a tabulation character seems to be interpreted by JavaCC as 8 characters)

[ADQL] Fix DEBUG mode in the ADQL parser. It is still by default disabled, but now, it is possible again to enable it using the function 'setDebug(boolean)'.

[TAP] Fix NullPointerException in TAPConfiguration (this error happens only when a NoSuchMethodException occurs.

Permit ADQL library build for java5

You can now set the adql.bootclasspath system property to use
an alternative bootclasspath, for instance that for a different
JRE than that used by the compiler.

For instance, this cross-compiles to java 1.5:

   ant -Dant.build.javac.target=1.5
       -Dadql.bootclasspath=/usr/java/jdk1.5.0_22/jre/lib/rt.jar
       -f buildADQL.xml
       buildLib

Note the java used by ant has to be at least java 6 because of the
@Override source constructs on methods inherited from interfaces
(only methods from abstract or non-abstract classes can be annotated
with @Override in java 5).

Replace uses of String.isEmpty and Arrays.copyOf methods
(both introduced in java 6) with equivalent code that makes
use of only methods available in the java 5 runtime.
This allows the ADQL library, if cross-compiled for java 5,
to run without errors on a java 5 runtime.

[UWS] Fix bug in UWSServlet: the destroyJob action in POST must be tested before the setJobParam action....otherwise the setJobParam action is always applied which leads to a Forbidden error when trying to destroy a job.

[ADQL] Rename UnresolvedJoin and UnresolvedFunction so that normalizing all UnresolvedXxx exceptions.

[TAP] Upgrade STIL version + Specify charset encoding for Javadoc generation in all Ant build scripts.

[TAP] Add Javadoc for all TAP configuration file related classes + Improve the function ConfigurableServiceConnection.getFile(...) + Set the default value of limits/durations/periods to the maximum value if the new maximum value is less than the current default value.

[TAP] Incorrect setting of the backup frequency. The documentation was also incomplete about this property, but also wrong concerning the property backup_mode which is actually backup_by_user.

[UWS,TAP] Add the origin of the main exception after the exception class name in the log entries. This origin includes the class, the method, the file and the line where the exception has been thrown.

[TAP] Fix unterminated thread after a failed UPLOAD. This bug happened when an uploaded VOTable reading was interrupted by an exception (like a ParseException)....the streaming thread was not stopped and was still waiting for a notification in order to read the next row.

[TAP] Improve the default TAP service home page. Particularly, a form with a few basic javascript has been added.

[TAP] Correction of the default value for the upload_enabled property. By default, the UPLOAD feature is disabled.

[UWS,TAP] Fix regression: the log message for the event REQUEST_RECEIVED was not displayed any more.
