Re: Release Announcement: General Availability of JDK 10

[Vincent Privat]

Hi Rory,
Thanks for the heads-up.
I am particularly unhappy about [3] and [4] as Oracle is removing on
purpose key technologies used by JOSM, without replacement nor acceptable
explanation (for WebStart).
WebStart removal will have negative impacts for our project, this is not a
good news at all.
As a consequence I won't invest any second of my benevol time anymore to
help you to improve the adoption of JDK. I'm thinking in particular about
the previous request to try to enable JDK coverage in our unit tests. As we
have no interest in this, and Oracle has no interest in maintaining the key
technologies we use, I am sure you will understand.
Regards,
Vincent

Re: JOSM Memory usage with large files

[Vincent Privat]

Hello,
Can you please launch josm with "java -jar -Xmx4096M
-XX:+HeapDumpOnOutOfMemoryError josm-tested.jar" command line and share the
(compressed) resulting heap dump somewhere?
See
https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/clopts001.html
for details.
Cheers,
Vincent

JOSM Memory usage with large files

[Mike N]

Hi, we're working on an import (long announced and documented) of 
buildings in the area - I'm working with Windows with no problem 
-Xmx4096M , and Ubuntu with no problem.   Another mapper helping with 
the import is experiencing a problem in which the JOSM / java grabs a 
huge amount of memory such as 11-15G of RAM when editing or uploading a 
file consisting of 10K - 15K nodes / 3K buildings which brings the 
computer to a standstill since the computer only has 8G of RAM.


  What kinds of things could cause this problem, and what are some tips 
that might point us in the right direction?


  Thanks, system info follows.

8G physical RAM
