Help for Obfuscate4e to my Eclipse Rcp?

[David Song]

Hi all,
I use obfuscate4e(proguard) to obfuscate my eclipse rcp (jpa, hibernate, mysql), but get error just like below:

in addition，If I export my rcp application without using the obfuscate4e , my rcp app works well, but once using it , the rcp gets errors!

has the Swing problem also been obfuscated?
