Yep, this is the problem of LevelDBJni 1.8 on Windows. I've build the lib using LevelDB 1.18 which has no such problems but we didn't include this to release yet (since has to be tested more). You may include it yourself by fixing ethereum-core/build.gradle:

repositories {
    maven {
        url "http://dl.bintray.com/ethereum/maven"
    }
}
dependencies {
-    compile "org.ethereum:leveldbjni-all:1.8"
+    compile "org.ethereum:leveldbjni-all:1.18"
}

We will most likely replace it in the next upcoming release, so I will close this issue.

Also you will need to delete the database dir after the change
Thanks for reporting!

Hi Anton,

Sorry for the submission, I was afraid it might be something on my end.
Thank you for the help directing me how to get past it.

@Nashatyrev does the other dependencies like the below need to be removed also ?

remove compile "org.fusesource.leveldbjni:leveldbjni:1.8"
remove compile "org.fusesource.leveldbjni:leveldbjni-all:1.8"

add compile "org.ethereum:leveldbjni-all:1.18"`

@Nashatyrev , do you have a planned date for your next upcoming release?
We need an official jars...
Thanks!

I'm also getting the same error . Here is my gradle file :-

}
Please help me on that. After syncing for about 2 days , it is now showing this error again and again ..

@gitexperience Please upgrade to the latest release version:
compile 'org.ethereum:ethereumj-core:1.3.0-RELEASE'
