Comment 2 Petr Cyhelsky 2013-08-02 08:28:24 UTC

there are 10 instances of symtab, please evaluate

Comment 3 Jan Lahoda 2013-08-02 08:55:22 UTC

I guess this can be split into two distinct problems:
-the javac instances are too big - same as bug #231565 IMO (exact cause unknown)
-8 of the 10 instances of javac appear to be held by the debugger - feels like a little bit too much.

Comment 4 Martin Entlicher 2013-08-15 17:02:48 UTC

It looks like parseWhenScanFinishedReallyLazy() is scheduled several times.
