Bug#239452: ant: fails to compile previously working package

[Peter Eisentraut]

Package: ant
Version: 1.6.1-1
Severity: normal

I have installed

sablevm 1.1.0-5
classpath 0.07-2
jikes 1.18-8

and no other Java VMs, libraries, or compilers.

I am trying to build the PostgreSQL JDBC driver
(http://gborg.postgresql.org/project/pgjdbc/projdisplay.php, today's
checkout) with this setup.  With the previous ant version in Debian,
1.5.4-3, this worked.  With 1.6.1-1, I get

$ ant -Dbuild.compiler=jikes
[...]
compile:
    [javac] Compiling 80 source files to /home/peter/jdbc/pgjdbc/build
    [javac] Could not remove shutdown hook
