    cache.clear inside a batch

    clagio Newbie

      Hello,

      It's possible to use a cache.clear inside a batch transaction?

      I have a code like this:

      app.cache.startBatch();

      app.cache.clear();

      app.cache.put("k1","value1");

      app.cache.endBatch(true);

      Which gives the following error:

       

      ERROR: ISPN000136: Error executing command SizeCommand, writing keys []

      java.lang.IllegalStateException: Transaction EmbeddedTransaction{xid=Xid{formatId=1, globalTransactionId=85C51E23E9A44DF629C6535A1060461F0000000000000003,branchQualifier=85C51E23E9A44DF629C6535A1060461F0000000000000003}, status=COMMITTED} is not in a valid state to be invoking cache operations on.

      If I move the cache.clear outside the batch, I don't have errors... Checking the code behind cache.clear in the Cache.java I see the following comment:

       

         /**
        * Removes all mappings from the cache.
        * <p/>
        * <b>Note:</b> This should never be invoked in production unless you can guarantee no other invocations are ran
        * concurrently.
        * <p/>

        * If the cache is transactional, it will not interact with the transaction.

       

      Could be that there is a conflict between the startbatch transaction and the transaction (?) started by the cache.clear?

       

      Thanks
