[rules-dev] an occasional error, I can never remember the cause... (JavaDialect)

[Michael Neale]

java.lang.NoClassDefFoundError: Could not initialize class
org.drools.rule.builder.dialect.java.JavaDialect
        at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.newDialect(JavaDialectConfiguration.java:65)
        at org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry(PackageBuilderConfiguration.java:291)
        at org.drools.compiler.PackageRegistry.<init>(PackageRegistry.java:24)

Do others see this? I am sure I have battled it before, but every time
I seem to forget what I did to make it go away (perhaps a different
thing each time).

Any ideas?
