"IllegalArgumentException: new file overlaps existing files in range" on put

[Yavor Nikolov]

When I run a put( key, value ) loop over index from 0 to 25 million (the error is raised soon after 300 000) I'm often (though not always) getting following exception:

org.iq80.leveldb.impl.DbImpl$BackgroundProcessingException: java.lang.IllegalArgumentException: new file overlaps existing files in range
    at org.iq80.leveldb.impl.DbImpl.checkBackgroundException(DbImpl.java:386)
    at org.iq80.leveldb.impl.DbImpl.writeInternal(DbImpl.java:636)
    at org.iq80.leveldb.impl.DbImpl.put(DbImpl.java:602)
    at org.iq80.leveldb.impl.DbImpl.put(DbImpl.java:595)
...

Keys/values are like that (converted to bytes via getBytes( "UTF-8" ):

keys:  "Key LOOOOOOOOOOOOOOOOOONG KEY " + index;
values:  "This is element " + index + "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAABZASDFASDKLFJASDFKJSDFLKSDJFLKJSDHFLKJHSDJFSDFHJASDFLKJSDF";

The error was reproduced with and without compression. Also with default (4K) and with 32K block size. And in general - I'm testing with default options (just createIfMissing is changed to true). And I'm always starting with clean folder used for database path.

The same thing with shorter key/value ( "Key " + index, "Value " + index ) worked without any errors.

Reproduced with:

• Oracle JRockit(R) (build R28.2.4-14-151097-1.6.0_33-20120618-1634-linux-x86_64, compiled mode)
• Java(TM) SE Runtime Environment (build 1.7.0_07-b10) /Linux x86-64/
• Java(TM) SE Runtime Environment (build 1.6.0_33-b03)
