Database connection profiles dissappear after restarting 7.0

Hi all,

I've had this issue since 6.x, hoped moving to 7.x would fix it. I generally want about 20 database connection profiles in my Services->Databases list. They're all MySQL connections, to either a local db, or via ssh tunnels to remote databases. I create them by right clicking the "Databases" root node, choosing New Connection, driver "MySQL (Connector/J Driver)" (the default .jar shipped with netbeans, which never changes), and setting up the connection settings. Nothing unusual here.

I often find that restarting netbeans results in a few of them disappearing. They don't appear in the list. I can re-create them, use them happily for a few days, and after some time restart Netbeans and find they're gone. I can't tell if it's the same ones that keep disappearing, I'm never paying close enough attention to notice which ones are there and which not.

I've noticed ~/.netbeans/7.0/config/Databases/Connections, in which I have 60 xml files. Only 12 of them have content, the others are 0 bytes long. Only those with content result in a Databases node. This morning, I find 12 nodes in my Databases list, and only 12 of the 60 files have content (about 400 bytes each). They're all owned by my user, permissions are good, I can see no problems with reading/writing these files.

So, it seems something is causing these jdbc_mysql___host_post_stuff.xml files to be truncated, or wiped somehow.

Is there a log I can monitor that might tell me when this is happening?

I've removed the 0 byte xml files and will monitor the situation to see if I notice any other useful info. The problem might have gone away now that I've cleared away the crufty files.

Well, it just happened again. Seems to be related to closing Netbeans.

- booted machine this morning, worked until about 11:30am, quit netbeans by clicking the 'x' in the title bar, waited a few minutes doing other tasks, rebooted machine.
- on reboot, loaded netbeans, two connection profiles that I created yesterday are gone.
