This issue occurs only under `MetalLookAndFeel` on Linux. It was introduced by [JDK-8040630](https://bugs.openjdk.java.net/browse/JDK-8040630) fix.
> component.setBounds(ownerX, ownerY, 1, 1); This line adds an extra reshape call with `1x1` size right before getting another one with correct sizes. If `MetalToolTipUI#paint()` call happens before getting correct sizes, it calculates `paintTextR` with negative sizes for component with `1x1` size, thus IAE is thrown. The fix is to do not proceed with `paint()` for negative sizes. The provided test fails for me in 0-30s interval(before the fix), other testing(client-tier1,2,3) looks good. ------------- Commit messages: - reduce timeout - initial Changes: https://git.openjdk.java.net/jdk/pull/2761/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=2761&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8262085 Stats: 160 lines in 2 files changed: 157 ins; 2 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/2761.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/2761/head:pull/2761 PR: https://git.openjdk.java.net/jdk/pull/2761
