crashes when used with short string properties with compression enabled

[freeeve]

Here's the full stack trace. When I disable compression it goes away. Probably an issue in MapDB, but I'll post this here for now.

[jexp]

@jankotek have you seen this before? This tests stores string keys with a long array as value in a tree map.

[jankotek]

No, looks like there is error on compression library I am using. There is thread to discuss alternative compressions:
jankotek/mapdb#81

[jankotek]

This should be fixed now in snapshot
jankotek/mapdb@2d4fa72

[freeeve]

Thanks @jankotek ! I'll give it a try.
