re xerces, we'd also need to exclude it from the JTS dependency: [INFO] | +- com.vividsolutions:jts:jar:1.12:compile [INFO] | | \- xerces:xercesImpl:jar:2.7.1:compile (version managed from 2.4.0)
I'm in favor of reducing the number of embedded databases, but taking bdb je off might be good enough for the time being. The effort of writing a new epsg factory might not worth the benefit if only looking to reducing the permgen stress. I _think_ heavy use of dynamic proxies and bytecode instrumentation (although it doesn't look like we have cglib in the classpath) makes for more classes loaded than a small lib like hsql. Yet a worthy goal for general consistency perhaps. On the other hand, the JVM permgen space is going to be removed[1] in upcoming updates of the oracle jvm as they integrate more JRockIt code, and it is already removed on OpenJDK[1] So +1 on removing unnecessary/overlapping dependencies, but not so sure permgen is _the_ motivation to do that.
