Hi All,
When we install DAS features to CDMF(This already have the APIM features),
found a weird fatal exception which failed to start the synapse.
[2015-09-30 18:23:51,439] INFO

[2015-09-30 18:23:51,474] FATAL
{org.wso2.carbon.mediation.initializer.ServiceBusInitializer} - Failed to
initialize ESB due to a fatal error
java.lang.VerifyError: Bad type on operand stack
Exception Details:
Location:
org/apache/synapse/config/SynapseConfigUtils.getURLConnection(Ljava/net/URL;)Ljava/net/URLConnection;
@289: invokevirtual
Reason:
Type 'java/lang/Object' (current frame, stack[0]) is not assignable to
'java/net/URLConnection'
Current Frame:
bci: @289
flags: { }
locals: { 'java/net/URL', 'java/lang/Object', 'java/util/Properties',
'java/lang/String', 'java/lang/String', 'java/util/List',
'java/lang/String', 'java/lang/String', 'java/lang/String', '[B',
'java/lang/String' }
stack: { 'java/lang/Object', 'java/lang/String', 'java/lang/String' }
Bytecode:
0000000: 2ac7 001a b200 01b9 0020 0100 9900 0db2
So when digged through the cause of this exception, I was able re-produce
this error by only installing the analytics-core feature[1]. Further I was
able find that the below bundle caused this exception.
<bundleDef>org.wso2.orbit.org.ow2.asm:asm-all</bundleDef>[2]
This can also be produced on the ESB 4.9.0 by installing the analytics-core
feature.
The above exception was solved by deleting the above (asm-all) dependency
on the pack.
I wonder why this dependency is causing the synapse failure ?. Any thoughts
on this would be helpful.
