Bug#706176: FTBFS with hsqldb 2.2.9: cannot find symbol (org.hsqldb.Trace)

[Rene Engelhard]

Package: openjpa
Version: 2.0.1-1
Severity: important
Tags: experimental

I just tried to build openjpa with libhsqldb-java 2.2.9 in preparation of
#670902.

It failed:

[...]

I am filing this as important now but it will become serious when
libhsqldb-java 2.2.9 will replace the obsolete 1.8.0 in sid. Which 
will be the case shortly after wheezy release (when LO 4.0 gets uploaded.)
