3. The Universal Plugin Manager is non-functional

原因

1. Using a version of Java < 1.6.0_4. The correct version of JAXB did not get added to the JDK until 1.6.0_4
2. Using FreeBSD, you'll notice that the latest version is 1.6.0.3p4_29.

ソリューション

For the first cause:

Upgrade the JDK past 1.6.0_4, eg. JVM 6 Update 17. Do not upgrade to JVM 6 Update 18 or later due to a stability issue, refer to Fatal JVM Crash - 'java.lang.OutOfMemoryError .. Out of Swap Space?'.

For the second cause:

Download Diablo JDK16 and point the JAVA_HOME to Diablo JDK
