Cause:
=====
The designer.tra file may be pointing to a version of JRE older than 1.6.0 .


Resolution:
==========
Using BE 4.0 palettes in Designer requires the use of JRE 1.6.0. Point the designer.tra file from JRE 1.5.0 or older version to JRE 1.6.0.

NOTE: Remember to change the values of all the three given JVM variables -
          tibco.env.JVM_LIB_PATH=
          tibco.env.JVM_LIB_DIR=
          tibco.env.TIB_JAVA_HOME=
