-------------------------------------------
Hi Willem,
Thanks a lot for the workaround!
Seems, that it's a bug in the felix, as the following snippet in the
GroovyExpression#evaluate(Exchange, Class)
{code}
System.out.printf("Script type: %s@%s%n", scriptType.getName(),
System.identityHashCode(scriptType));
Object o = scriptType.newInstance();
System.out.printf("Script instance: %s@%s%n", o.getClass().getName(),
System.identityHashCode(o));
System.out.printf("Script instance superclass: %s@%s%n",
o.getClass().getSuperclass().getName(),
System.identityHashCode(o.getClass().getSuperclass()));
System.out.printf("Script.class: %s@%s%n", Script.class.getName(),
System.identityHashCode(Script.class));
System.out.printf("Script.type classloader: %s@%s%n",
scriptType.getClassLoader().getClass().getName(),
System.identityHashCode(scriptType.getClassLoader()));
System.out.printf("Script.instance classloader: %s@%s%n",
o.getClass().getClassLoader().getClass().getName(),
System.identityHashCode(o.getClass().getClassLoader()));
System.out.printf("Script.class classloader: %s@%s%n",
Script.class.getClassLoader().getClass().getName(),
System.identityHashCode(Script.class.getClassLoader()));
{code}
outputs the following for the passed test
{code}
Script type: script13454122538541505912543@999191884
Script instance: script13454122538541505912543@681806680
Script instance superclass: groovy.lang.Script@765505133
Script.class: groovy.lang.Script@765505133
Script.type classloader: groovy.lang.GroovyClassLoader$InnerLoader@1915502523
Script.instance classloader:
groovy.lang.GroovyClassLoader$InnerLoader@1915502523
{code}
and outputs the following for the failed test
{code}
Script type: script13454122770291505912543@1670892698
Script instance: script13454122770291505912543@1556003292
Script instance superclass: groovy.lang.Script@798159189
Script.class: groovy.lang.Script@1292687619
Script.type classloader: groovy.lang.GroovyClassLoader$InnerLoader@1694302424
Script.instance classloader:
groovy.lang.GroovyClassLoader$InnerLoader@1694302424
{code}
Script.class and Script instance superclass must be the same classes, but in
the case of lazy bundle activation and felix framework they are different.
> GroovyLanguage should use applicationContextClassLoader of the corresponding
> CamelContext instead of current thread's contextClassLoader
