Is it possible to slip a light version of rt.jar for the IntelliJ IDEA IDE?

Question

Java

Friends. The problem is this. There is a 2Gb RAM
netbook with an Intel Atom x2 CPU . I am writing in Java in IntelliJ IDEA CE 14 , indexing takes a very long time. Autocomplete is also very long. I think you can somehow increase the performance of the IDE. Is there any way to truncate rt.jar ? For me, for example, AWT and Swing are not needed (it is possible to exclude other packages in the future). And then feed it to the IDE . Is it possible to do this hack? PS All unnecessary plugins are off, I transferred the indexing file to memory and for the IDE itself I use JDK 6 version.

Answer 1

by deleting classes from rt.jar, you can only free up disk space, only the
java 8 classes necessary for work are loaded into memory in some places up to 30% faster than the 6th

Answer 2

do you have an ssd?
