OutOfMemoryError: PermGenSpace from HQL console

Description

The HQL Console eventual throws an OOME due to PermGenSpace running out – looks like there's a leak in there somewhere, probably related to exception handling, since I can't seem to get the console to work at all (IDEA-15917).

8062: at least one leak is the following:
1. Open project with hibernate configuration. Check the permanent memory usage (e.g. with jstat).
2. Open HQL console. Run query (my query selects 2 records from 1 table).
3. Close console, close project.
4. Reopen project, open console, run the same query. Check the permanent memory usage: it's grown in 4Mb.
Repeat again: memory usage is 4Mb more again.
The essential condition to reproduce is closing and opening projects. Whithout this there is no leak.
