I've rendered it with Java 8 and it took ~27 sec. hanging several times in the stack you've mentioned, because of some bad scaling values. Then I've tried Java 14 and it took ~2 sec. Which Java version are you using? I've rendered it with Java 8 and it took ~27 sec. hanging several times in the stack you've mentioned, because of some bad scaling values. Then I've tried Java 14 and it took ~2 sec. Which Java version are you using? Java 8. Oracle Java 1.8.0_161-b12 on a Mac hangs effectively forever. I gave up after an hour. I should add we've also tried this under OpenJDK 1.8.0_252-b09 on CentOS and seen the same effectively infinite hand. Although when running this on OpenJDK (build 1.8.0_265-8u265-b01-0ubuntu2~20.04-b01) it took 52sec, you might want to enable the marlin engine. see https://github.com/AdoptOpenJDK/openjdk-build/issues/716 for details tl;dr: * download the jar from https://github.com/bourgesl/marlin-renderer/releases/tag/v0_9_4_3 * add -Dsun.java2d.renderer=org.marlin.pisces.MarlinRenderingEngine -Xbootclasspath/a:<path>/marlin-0.9.4.3-Unsafe.jar or if you are updating to u262 and later you can use: -Dsun.java2d.renderer=sun.java2d.marlin.MarlinRenderingEngine |
