This article argues about four EU countries sending ambassadors to attend the official inauguration of the US embassy in Jerusalem:
Breaking with European consensus, the ambassadors of four EU countries are set to attend a reception Sunday at the Foreign Ministry in honor of the official inauguration of the US embassy in Jerusalem this week.
The Foreign Ministry invited 86 foreign ambassadors stationed in Israel to the event, a day before the official move. About 40 of them announced their participation, Foreign Ministry spokesperson Emmanuel Nahshon said Saturday, including Austria, Czech Republic, Romania, and Hungary.

Most European countries have slammed US President Donald Trump’s move as not in line with international consensus, preferring to wait on recognizing the city until the status of Jerusalem is finalized in talks with the Palestinians.
So the EU seems reserved when it comes to this very sensitive matter, probably because it favors two state solution:
Commissioner for Neighbourhood and Enlargement Negotiations, Johannes Hahn, commented: “The EU remains committed to the two-state solution and will therefore continue to support the Palestinian Authority in its state-building efforts and in delivering basic social services. Our support remains the quickest and most effective way to deliver funding to the Palestinians, including those living in Gaza, in a moment of severe difficulties”.
Question: Why did the four countries break the EU consensus over the US embassy in Jerusalem?
For Romania I assume it is related to the US-Romania Strategic Partnership. I find Austria's case particularly interesting due to its neutrality.
