Re: [libreoffice-users] Re: LibreOffice-Base CPU usage

Hi :)
Java is an unusual problem for LibreOffice.  Most of the apps have either already moved away from 
it or are moving away fast.  Java and OpenJdk are owned by Oracle.  Do we have any confidence in
them fixing things so that their products work better for LibreOffice?  Currently the newer the 
release of Java the more problems there seems to be in using it in LibreOffice.  

I don't think there was a bug-report.  There are almost no devs working on Base so posting a 
bug-report is not likely to yield any positive results for months, maybe years.  Also if devs do 
start working on Base it would be good to follow the rest of the project away from java.  
Inevitably devs are going to have to start by fixing bugs but any work they do to fix problems with 
java will have been a bit of a waste of time after java is written out.  

It's NOT ideal for LO but we have to deal with things as they are rather than how we would like 
them to be.  We can temporarily work-around problems by using the _21 (or _20 or _22) and by trying 
to encourage people to develop Base's code.  

The SC wants to sit&wait to see if anyone happens to notice that working on Base might be a 
rewarding challenge.  When pushed they thought it might be nice to make a questionnaire to send to 
people who don't need a database program to ask them what they want from a database.  
Regards from
Tom :)

Please provide a link to your bug reports (for both LO and Java). Thanks.
