The Curse of Jeconiah

After the godly king Josiah, there were only ungodly kings in Judah:

1. Shallum/Jehoahaz: Josiah's 4th son, reigned three months.
2. Jehoiakim/Eliakim: Josiah's 2nd son, reigned eleven years. 
3. Jeconiah/Coniah/Jehoiachin: Jehoiakim's son, reigned three months.
4. Zedekiah/Mattaniah: Josiah's 3rd son, reigned eleven years, see
   Zedekiah of Judah in Kings of Judah and Israel. He was the last king of Judah, followed by the Babylonian captivity.

Johanan, who was Josiah's 1st son (1 Cron 3:15), isn't mentioned as king in Judah.
He also has the name Jeconiah (Mat 1:11). That's the same name as the cursed one.

Jeconiah

Jeconiah was the penultimate king of Judah before the Babylonian captivity,
see Jehoiachin in the beginning of Visions and Dreams by Prophet Daniel. 

Jeconiah (1 Chron 3:16, Jer 24:1, 27:20, 28:4) is the same man as Coniah 
(Jer 22:24, 37:1) and Jehoiachin (2 Kings 24:6, 2 Chron 36:8). 
The question is whether he is also the same man as Jeconiah (Mat 1:11)
who is part of Jesus' family line.

King Jehoiachin (Jeconiah) did evil things in the eyes of the Lord 
(2 Kings 24:8–16). Jeremiah pronounced a curse over him (Jer 22:24–30):
None of his offspring would succeed in sitting on David's throne and reigning in Judah again. That would indicate that the genealogy of Jesus in Matthew is a cursed family line, if Jeconiah in Mat 1:11 is the same person. If so, that disqualifies Jesus from being Messiah, as he has no right to the throne of David.

King Jehoiachin's (Jeconiah's) father was Jehoiakim (2 Chron 36:8, 2 Kings 24:6).

Jehoiakim was a brother of Jehoahaz (2 Chron 36:4, 2 Kings 23:34).

Jehoahaz's father was Josiah (2 Chron 36:1, 2 Kings 23:30–31).

This gives the genealogy:
King Josiah → king Jehoiakim → king Jehoiachin (Jeconiah) (who was cursed).

The genealogy in Mat 1:11 is as follows:
King Josiah → Jeconiah (brother or half-brother to king Jehoiakim above).
Jeconiah is the same person as Johanan, Josiah's firstborn (1 Cron 3:15).

This means that Jeconiah in Jesus' genealogy isn't the same person as the cursed Jehoiachin in Jeremiah. This means that Jesus' genealogy isn't cursed,
and that Jesus can be Messiah.

This is detailed described with more explanations in the video The Curse of Jeconiah.

Jehoiakim

Jeremiah had written down on a scroll all the words that the Lord had spoken to him against Israel and Judah. It was reported to Jehoiakim, king of Judah (father of the cursed Jehoiachin), who sent for the scroll and it was read to him. When three or four columns were read to Jehoiakim, he cut them off with a knife and threw them into the fire in the fiery cauldron, until the whole scroll was consumed. Neither the king nor any of his servants who heard all these words were afraid, and they didn't tear their garments. After the king burned the scroll, the Lord told Jeremiah to write all the previous words that were on the first burned scroll on another. The Lord said of Jehoiakim that he would have no one to sit on David's throne, and his dead body would be thrown out into the heat by day and the frost by night. The Lord would punish him and his offspring for their iniquity. (Jer 36:1–32).

Jehoiakim's son Jehoiachin reigned for only three months before being exiled
by Nebuchadnezzar, fulfilling the prophecy of no permanent successor.

Jehoiakim showed no respect, fear, or honor for God's Word, see 
To Fear the Lord in Fear of Man. He wasn't part of Jesus' genealogy.
