Summary0045729: export.database fails with some views on oracle with: An invalid XML character (Unicode: 0x0) was found in the CDATA section.
DescriptionProblem was found in one specific environment for 3 specific views.

Running export.database with the module in development containing those views fails with:
     [java] Caused by: org.apache.ddlutils.DdlUtilsException: An invalid XML character (Unicode: 0x0) was found in the CDATA section. : /srv/ci/workspace/mod-simple-ci34.18102/modules/org.openbravo.cashposition/src-db/database/model/views/OBCP_ACTUALS_V.xml

     [java] at org.openbravo.ddlutils.task.ExportDatabase.execute(ExportDatabase.java:211)

Technically errors comes from code inside export.database re-reading the just exported xml definition files and failing the the export did write wrong data into them.

Comparing diff of the wrong view to earlier state shows that 1 or 3 0x0 byte '0' are added just after the view definition itself inside the CDATA section.

The attached diff shows the wrong data.

Trigger for when this error is happening + cause of adding 1 or 3 of those bytes is currently unclear.
Problem can be reproduced 100% reliably in one environment.

This code-snapshot file and revision can reproduce the problem:

Steps To ReproduceClone above code-snapshot
run install.source on oracle
run all modules with type <>'T' into development
run export.database

Probably just exporting this specific module: "org.openbravo.cashposition" is enough to reproduce the problem

The 3 xml files attached are the 3 views triggering the problem (just for easy access. They are contained in the code-snapshot referenced above)

ISSUE-45729: Workaround reading some views on oracle (extra 0x0 bytes)

Some specific views when having their definition read from the database
fail as they have 1-3 0x0 bytes just after their view body.

That works around strange Oracle behavior (probably caused by
USER_VIEWS.TEXT column we read here having 'LONG' data type and that
datatype has some quirks and is marked 'do not use me' (but used in that
internal ORACLE view).

Apply trim() to the String value read which will strip out any
whitespace (including 0x0) before post-processing it.

We already strip out \n (newlines) from view bodies and even .trim() the
result of the PG translation.
