I just noticed my client was there hanging. After restarting and loading up wallet i got  exception you can see below. Is it due to network down? v1.0.11 loads up wallet.

v1.0.12 just gives:
"Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap"

Memory leak? I had 0.11 running for probably 2 days with no other java soft that i can recall. Win 10 x64/java 8u144 32bit.

edit: computer reset did not help, so not mem leak. Kind of bummer if one can't access wallet if there is no connection to network
