Hi,

the line find_java_runtime java6 is basically correct. It is the minimum

Actually making the Oracle JDK the preferred JDK via the alternative
mechanism:

update-alternatives --config java

should resolve your issue. If not, then we have a bug in java-wrappers.
It seems this is the case. I've done this right after the installation 
of Oracle 8u152.
After reading a little bit about the find_java_runtime function, it 
seems that it only uses the alternatives list if it gets no parameter.



If two java8 JRE are installed on the same system, java-wrappers should
detect and use the one which is the preferred JRE based on the
update-alternative mechanism.

If you are really sure that the Oracle JRE is already the preferred one,
please report back and I'm going to reassign this bug report to
java-wrappers. The real issue is in openjdk though but this will be
fixed eventually.
Yes, I'm absolutely sure I've set the default. At one point I even tried 
to set the /usr/lib/jvm/default-java symlink to point to the newly 
installed directory but this got ignored as well.


So please reassign this bug.
As a side note the documentation of find_java_runtime doesn't really 
mention the role of the parameter (it's the minimum version or the 
wanted version), so maybe this should be fixed as well.


Best regards,
Tylla

Hi,

the line find_java_runtime java6 is basically correct. It is the minimum
requirement for running Sweethome3d. Nowadays it should be java7 though
because java6 is no longer supported in Debian.

Actually making the Oracle JDK the preferred JDK via the alternative
mechanism:

update-alternatives --config java

should resolve your issue. If not, then we have a bug in java-wrappers.

update-alternative mechanism.

If you are really sure that the Oracle JRE is already the preferred one,

Yes, I am certain that the "java6" was added to prefer the java6 runtime
on systems where java5 was also installed, but now it seems to be having
an undesired effect.  So it sounds like we have a bug in the
"javahelper" package as well.

Also, thank you for the information about the cursor CopyDrop.32x32
issue.

Cheers,
tony

Package: sweethome3d
Version: 5.6+dfsg-1
Severity: important
Tags: patch

After installing the latest version (5.6+dfsg-1 from buster) of Sweethome3D on
my laptop (Lenovo X201) I came across the problem that I could not start the
program.
---> (to cut short the explanation there is a worksforme solution at the end)
Trying to start it from the console revealed that it crashed with an exception:
