Calling `DefaultTableModel.setColumnIdentifiers()` resizes the row height of the table to default row height (16) even if the row height is changed to something other than the default using J`Table.setRowHeight(row, height). ` The spec of `DefaultTableModel.setColumnIdentifiers()` https://docs.oracle.com/en/java/javase/24/docs/api/java.desktop/javax/swing/table/DefaultTableModel.html#setColumnIdentifiers(java.lang.Object[]) says that it `replaces the column identifiers in the model`, that is, the header field of the column is changed to the passed identifier and nowhere it is mentioned that row height would be changed.
The issue happens because calling `DefaultTableModel.setColumnIdentifiers()` results in the firing of a `TableModelEvent` with HEADER_ROW event and JTable resets the `rowModel` for it irrespective of what the event is. Fix is to not reset the `rowModel` to keep the set rowHeight intact for HEADER_ROW event No other issue observed with CI with this fix.. ------------- Commit messages: - jcheck - JDK-6292135:DefaultTableModel.setColumnIdentifiers() Clears JTable Row Heights Changes: https://git.openjdk.org/jdk/pull/28529/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=28529&range=00 Issue: https://bugs.openjdk.org/browse/JDK-6292135 Stats: 101 lines in 2 files changed: 99 ins; 2 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/28529.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/28529/head:pull/28529 PR: https://git.openjdk.org/jdk/pull/28529
