Hi,
I'm having troubles with Blob fields after upgrading to Apache Isis
1.16.2 (not sure if this was also the case for 1.16.[0-1]). The feature
is using existing data we had no problems with before upgrading.
My field definition:
@javax.jdo.annotations.Persistent(defaultFetchGroup="false", columns = {
@javax.jdo.annotations.Column(name = "file_name",
allowsNull = "false"),
@javax.jdo.annotations.Column(name = "file_mimetype",
allowsNull = "false"),
@javax.jdo.annotations.Column(name = "file_bytes",
jdbcType="BLOB", sqlType = "BLOB", allowsNull = "false")
})
@Property(editing=Editing.DISABLED, optionality=Optionality.MANDATORY)
@Getter @Setter
private Blob file;
Caused by: javax.jdo.JDOFatalUserException: StreamCorruptedException:
object is corrupted
NestedThrowables:
java.io.StreamCorruptedException: invalid stream header: 47657370

I've changed the sqlType to "LONGVARBINARY" but this didn't help. I
can't reproduce this issue in the quickstart app. Was there any change
in Datanucleus version? Will have another look at the change logs.
Anyone having an idea?
Thanks,
Erik
