Hi,
I could narrow the window into r3723-r3732
r3723-CORE - works OK, memory consumption goes down after deleting the layer.
r3727-CORE - does not open the test jml file - I think it reads is totally but
at the end throws
java.lang.IllegalArgumentException: Tunnistamaton ominaisuustiedon nimi:

r3732-PLUS - OJ reserved memory stays in 3 GB after deleting the layer and
doing carbage collect.
Is this enough for an evidence that something evil happened between r3723 and
r3732?
It is nice to have snapshot builds available. It would be even more nice if we
had also some tests to verify if the builds are good and that they really start
with 32-bit and 64-bit jre. Now there are a few revisions around r3730 which do
not start at all, at least if the version is CORE and jre is 64-bit.
