Summary: GUI freezes when connection times out

Initial Comment:
Running:
- Linux Mint 12 (AMD64)
- Eclipse 3.7.1
- OpenJDK 1.6.0_23-b23
- SQL Explorer 3.6.1
- db2jcc4-9.7.100.177.jar connector

Open a connection to a database, and allow the connection to time out. After time out, try to close the connection. The entire GUI freezes up and has to be force-killed.

FYI: I have seen this exact same behaviour with SQuirreL, which I believe SQL Explorer is at least partially based on.

Message:
Probably this is a problem with the underlying db2 JDBC driver. The call to
close the connection on a timed out connection will never return.
A workaround is to use the new preference:
Close unused connections after (seconds)
If you set it to a value lesser then the db2 connection timeout the
connection is closed before time out. If you don't need connection specific
db values like temp tables or sql session values you can set this value as
small aus you like. SQL Explorer creates a new connection if required.
