> When the entry was overwritten without reading previous value and then we read it (this read is handled from the current context), write skew check is still applied and can fail, despite that it's unnecessary.
> {code:java}
> cache.put("k", "init");
> tm.begin();
> cache.getAdvancedCache().withFlags(Flag.IGNORE_RETURN_VALUES).put("k", "v1");
> assertEquals("v1", cache.put("k", "v2"));
> Transaction tx = tm.suspend();
> assertEquals("init", cache.put("k", "other"));
> tm.resume(tx);
> tm.commit(); // fails with WriteSkewCheckException
> {code}
