Kristian Waagan updated DERBY-5940:
-----------------------------------

    Attachment: derby-5940-1a-disable_secMec8_on_ARM.diff

Attaching patch 1a, which disables securityMechanism=8 in 
NSSecurityMechanismTest.
I verified the patch by tracing NetConnection.flowConnect. Forcing 
hasSufficientEntropy to false, the number of flows went down from 231 to 132.
I've also tested a very similar patch on the ASF ARM build farm.

Patch ready for review.

> The security mechanism strong password substitution (securityMechanism=8) 
> uses code that relies on entropy, which seems to be in short supply on some 
> ARM systems. This includes the ARM server farm available in the ASF 
> build/test farm.
> I will disable tests using strong password substitution in 
> NSSecurityMechanismTest on ARM platforms to be able to run the test to 
> completion within a reasonable time.
> DERBY-3106 and DERBY-5651 are relevant.
