[Star Wars] Did Obi-Wan and Yoda come to realize that the Jedi way was fundamentally flawed (i.e. "wrong"), or did they simply believe it was all Anakin's fault?

I believe that in the RoTS novelization, Yoda comes to the realization that the Sith have been constantly evolving and adapting, while the Jedi have become stagnant. 

Yet, when training Luke to become a Jedi, neither Yoda or Obi-Wan concede that -- as long as it is not obsession -- love is a *good* thing and can strengthen oneself. They never seem to blame themselves for not being the support system that Anakin so desperately required -- rather that Anakin didn't commit himself to being a "proper" Jedi. Did they (ever) come to realize that the ways of the Old Jedi were fundamentally wrong and needed major adjustments?

In many ways, yes. But probably not in the ways that truly mattered.

Once the Jedi order was destroyed and the survivors left with nothing but themselves and the Force, they realized where they had gone wrong. Both Yoda and Obi Wan especially realized they placed their faith in the wrong people until it was too late, and relied too much on old texts and stagnant traditions to the detriment of the living force. Qui-Gon brought them both back to that line of thinking from beyond the grave. 

But having said that, they still considered themselves to be fighting a war. Obi Wan especially mistakenly assumed Luke to be the chosen one after Anakin broke his heart. Yoda was intent on training Skywalker's children (especially Leia, which is an interesting new addition to canon), but only as weapons to defeat the Sith. They were never going to be "proper" Jedi in the vein of those trained in the temple for the past thousand years. They were going to be given specific instructions and then told to go kill the Sith. 

That's where Luke comes in. His outsider perspective taught him that the constant fighting between Sith and Jedi was the wrong path. When he threw his lightsaber away and refused to keep fighting his father, he declared himself a Jedi. But not a Jedi like Obi Wan or Yoda, but of a new kind. Or perhaps a return to the old Jedi, before the stagnation and degradation. That's one reason in his old age, Luke became so despondent as his instinctive knowledge of the force clashed with a thousand years of "wisdom" accrued by a fundamentally mistaken order. 

It wasn't until after death that Yoda finally realized the true nature of the Jedi, and how it flows with the heart, not constrained by the mind. Hence why he wasn't upset about THE SACRED TEXTS. And his confidence in Rey.
