Created attachment 833117 [details] Developer guide
Wow, you're fast! Few details yet 22.1.4. Write Skew Checks "Use the REPEATABLE_READ isolation level to enable write skew check" -> this is formulated incorrectly. REPEATABLE_READ is needed, but it alone does not enable the write skew check. "With optimistic transactions, write skew checks are required for (atomic) conditional operations." - please, put this into Important box. Procedure 22.1., step 1) - please fix the indentation of ellipsis Procedure 22.2. - could you enable the code highlighting? step 2) "avilable" -> "available"

This paragraph is not a procedure for enabling WSC, it lists necessary conditions. None of those will enable WSC.
The fix for this bug is now generally released and available here: https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Data_Grid/6.2/index.html
