EclipseのUPDATEをかけたら、ばばーんと、「始動エラー」。いきなり、Eclipseが起動できなくて、ビビる。

むむむ。なんだこりゃ。

こんな時は、Eclipse.iniをあさってみるのが一番。
MACの場合、Finderを起動→Eclipse.appを選び「パッケージの内容を表示」を選択。そうすると、MacOSフォルダの中に、Eclipse.iniが見つかる。

そのまま、Eclipse.iniを開き編集。ただ怖いから、バックアップも1つ取っておく。削除しては起動しての繰り返しをしていたら、「-vmargs」の一行を削除した後に無事起動できた。他にもチェックするところあるかもしれないけど、とりあえず、起動したのでヨシとしよう。

うっかり、updateかけない方がいいなー。
