Hi Thomas,
I have some classes loaded by custom URL class loaders at runtime.
I have set that property with the -D switch for my application.
That leads to the following stacktrace:
Thread [Thread-70] (Suspended)
owns: HashMap<K,V> (id=58)
Utils.<clinit>() line: 76 <--- static block refers
to SysProperties.JAVA_OBJECT_SERIALIZE, but that static field has not been
initialized yet (as the Sysproperties clinit is still running)
SysProperties.<clinit>() line: 51 <--- initialization of
SysProperties class is still in progress
Engine.<init>() line: 32
Engine.<clinit>() line: 29 [local variables unavailable]
[...]
Kind regards,
Christoff Schmitz

I don't understand. As far as I see, it _is_ a separate topic (email
subject).

Why can't you use the default serialization mechanism? What problem do you
want to solve?
> because the Utils class is loaded when the SysProperties class is loaded
Yes. Why can't you set the system property before it is loaded?

Thomas

Hi,
I have set a custom serializer for Java object contained in columns of
type OTHER (added JAVA_OBJECT_SERIALIZER='custom.h2.Serializer' to the
connect string)
In H2 code, there are 2 calls to Utils.serialize (H2 1.3.176) [or
JdbcUtils.serialize (in H2 1.4.187)] that pass a NULL argument for the
data handler parameter.
Unfortunatly, my code runs into one of these (in org.h2.value.
ValueJavaObject), and my custom serializer is not used.
Additionally, I tried to use the system propoerty
"h2.javaObjectSerializer". But this did not help either (H2 1.3.176),
because the Utils class is loaded when the SysProperties class is loaded
(due to public static final String FILE_ENCODIN = Utils.getProperty(
"file.encoding", "Cp1252")). At that point of time, the SysProperties
class is not fully initialized yet, and the static block in Utils always
refers to NULL as serializer class name.
Seems a bit buggy to me.
Currently, my only workaround is setting the member "public static
JavaObjectSerializer serialize" of class Utils directly from my
application (H2 is used as embedded database).
Kind regards,
Christoff Schmitz
