Hello Greg,
I didn't noticed this on patchset 1 until now because I didn't have the new
eap from intellij, it seems that only with this last eap i get this NPE. But
now i can confirm that patchset 1 is affected too :(

But if I modify line 493 in Charset.java to check if cs is not null,
intellij's idea is working properly.
