OK.
> let's add such assert in TxManager.resumeTx.
It can't be done with simple assert since system transaction stored in map
`ConcurrentMap<TxThreadKey, IgniteInternalTx>`
So check would be something like this.
Is it OK?
{code:java}
if (!sysThreadMap.isEmpty()) {
for (GridCacheContext cacheCtx :
cctx.cache().context().cacheContexts()) {
if (!cacheCtx.systemTx())
continue;
if (sysThreadMap.containsKey(new TxThreadKey(threadId,
cacheCtx.cacheId())))
throw new IgniteCheckedException("Thread already start
system transaction.");
}
}
{code}
