Hi Peter,
The new versions of Bnd (post 0.0.198) appear to use a lot more memory
than they used to... for example almost 80m when bundling XML jarfiles.
I've tracked this down to additional data held in Clazz instances, which
are kept alive by the "classSpace" map in the Processor when analyzing
the bundle classpath.
Does the processor need to keep all this data, or can some of it be freed
after the class has been analyzed? (there is a reset method in Clazz - if
this is called after the class is processed then the memory usage drops
dramatically, but I'm not sure if calling reset affects later processing...)
Anyway, would appreciate it if you could look into this issue - thanks!
