Oracle has released Berkeley DB Java Edition 3.3.74. This is a non-relational embedded database written in Java. The data is exposed through a Java Collections-style interface, as well as a programmatic interface similar to the Berkeley DB API. According to Greg Burd, "3.3.74 is a patch release consisting of fixes for a number of significant issues. We strongly recommend that users of Berkeley DB Java Edition upgrade to this release. In particular we've fixed a potential data loss bug [#16523] that could cause LogFileNotFoundException in large databases where data is permanently lost. This bug can only occur in databases where a Btree's depth is > 3. The database must be at least 10 million records to be a candidate for this problem when using the default maximum entries per Btree node (128). This is only an approximation and the issue may occur under different circumstances when not using the default value of 128 (by calling DatabaseConfig.setNodeMaxEntries() to change that value)."
