The documentation set for JE includes:

This is release 3.2.76 of Berkeley DB Java Edition. The changes introduced in 3.2.76 consist of bug fixes, some additional minor functionality; the complete list of changes can also be found in the change log page.

Note: If you are using Mac OS X, please be aware of the following issue. Java version 1.4.2 on Mac OS X reports the wrong value for Runtime.maxMemory. JE calculates the default cache size as a percentage of maxMemory.  Because of this, for Java 1.4.2 on Mac OS X only, JE will assume that the Java maxMemory value is 64 MB.  With the default je.maxMemoryPercent configuration parameter (60%) the default JE cache size will be approximately 38 MB.  This default is fixed -- it does not change if the Java memory size is different than 64 MB.  To specify a different JE cache size, you must explicitly set the je.maxMemory configuration property.  The je.maxMemory property can be specified in the je.properties file or by calling EnvironmentConfig.setCacheSize.
