When attached sample is started with Java 7, it does not behave as expected (showing a single frame with a GLCanvas in it). Instead, most of the time it shows two frames of which one is called JavaEmbeddedFrame. On dual screen setups it can also end up in an infinite loop where the embedded frame is destroyed and created over and over. The issue does not occur with Java 6. The issue also does not occur when using a regular Canvas. This suggests that the bug is introduced in GLCanvas.java. 449 2013-04-03 15:29:23 +0200 2013-04-03 15:29:23 +0200 Sample code (needs JOGL and swt.jar) that illustrates the GLCanvas bug when ran on linux with java 7 GLSWT.java text/x-java 1434 bart.adams aW1wb3J0IG9yZy5lY2xpcHNlLnN3dC5TV1Q7CmltcG9ydCBvcmcuZWNsaXBzZS5zd3QuYXd0LlNX VF9BV1Q7CmltcG9ydCBvcmcuZWNsaXBzZS5zd3QubGF5b3V0LkZpbGxMYXlvdXQ7CmltcG9ydCBv cmcuZWNsaXBzZS5zd3Qud2lkZ2V0cy5Db21wb3NpdGU7CmltcG9ydCBvcmcuZWNsaXBzZS5zd3Qu d2lkZ2V0cy5EaXNwbGF5OwppbXBvcnQgb3JnLmVjbGlwc2Uuc3d0LndpZGdldHMuU2hlbGw7Cgpp bXBvcnQgamF2YXgubWVkaWEub3BlbmdsLmF3dC5HTENhbnZhczsKaW1wb3J0IGphdmEuYXd0Lio7 CgovKioKICAqIFNob3J0IHByb2dyYW0gdG8gaWxsdXN0cmF0ZSBhIEpPR0wgYnVnIHdoZW4gR0xD YW52YXMgaXMgdXNlZAogICogdXNpbmcgdGhlIFNXVF9BV1QgYnJpZGdlIG9uIGxpbnV4IHdpdGgg SmF2YSA3LgogICoKICAqIE5lZWRzIHN3dC5qYXIgYW5kIHRoZSBKT0dMIGxpYnJhcmllcy4KICAq LwpwdWJsaWMgY2xhc3MgR0xTV1QgewogIHB1YmxpYyBzdGF0aWMgdm9pZCBtYWluKCBTdHJpbmdb XSBhcmdzICkgewogICAgRGlzcGxheSBkaXNwbGF5ID0gbmV3IERpc3BsYXkoKTsKCiAgICBTaGVs bCBzaGVsbCA9IG5ldyBTaGVsbCggZGlzcGxheSwgU1dULlNIRUxMX1RSSU0gKTsKICAgIHNoZWxs LnNldExheW91dCggbmV3IEZpbGxMYXlvdXQoKSApOwogICAgc2hlbGwuc2V0VGV4dCggIlNXVCBB cHBsaWNhdGlvbiIgKTsKICAgIHNoZWxsLnNldFNpemUoIDY0MCwgNDgwICk7CgogICAgQ29tcG9z aXRlIGNvbXBvc2l0ZSA9IG5ldyBDb21wb3NpdGUoIHNoZWxsLCBTV1QuRU1CRURERUQgfCBTV1Qu Tk9fQkFDS0dST1VORCApOwogICAgY29tcG9zaXRlLnNldExheW91dCggbmV3IEZpbGxMYXlvdXQo KSApOwoKICAgIGZpbmFsIEZyYW1lIGZyYW1lID0gU1dUX0FXVC5uZXdfRnJhbWUoIGNvbXBvc2l0 ZSApOwoKICAgIGZyYW1lLnNldExheW91dCggbmV3IEJvcmRlckxheW91dCgpICk7CgogICAgLy8g UmVndWxhciBDYW52YXMgd29ya3MKICAgIC8vIGZyYW1lLmFkZCggbmV3IENhbnZhcygpLCBCb3Jk ZXJMYXlvdXQuQ0VOVEVSICk7CgogICAgLy8gR0xDYW52YXMgZG9lcyBub3Qgd29yazogc2hvd3Mg c2VwYXJhdGUgSmF2YUVtYmVkZGVkRnJhbWUgYW5kIHNvbWV0aW1lcyBlbnRlcnMgaW50byBhbiBp bmZpbml0ZSBsb29wIG9mIGRlc3Ryb3lpbmcgYW5kIGNyZWF0aW5nIGEgbmV3IGZyYW1lLgogICAg ZnJhbWUuYWRkKCBuZXcgR0xDYW52YXMoKSwgQm9yZGVyTGF5b3V0LkNFTlRFUiApOwoKICAgIHNo ZWxsLm9wZW4oKTsKICAgIHdoaWxlICggIXNoZWxsLmlzRGlzcG9zZWQoKSApIHsKICAgICAgaWYg KCAhZGlzcGxheS5yZWFkQW5kRGlzcGF0Y2goKSApIHsKICAgICAgICBkaXNwbGF5LnNsZWVwKCk7 CiAgICAgIH0KICAgIH0KICAgIGRpc3BsYXkuZGlzcG9zZSgpOwogICAgU3lzdGVtLmV4aXQoIDAg KTsKICB9Cn0K
