But you may keep both JVMS, or you may install even some more. In these cases javavmwrapper kicks in and lets you choose your preferred JVM. Unfortunately, javavmwrapper behaves differently, whether it sees an installed portstree (/usr/ports/Mk/bsd.java.mk) or not. It is my experience that the wanted priority of JVMs due to /usr/local/etc/javavms is only guaranteed, if there is no portstree available. So I decided to patch the javavm wrapper skript (/usr/local/bin/javavm) to remove these unwanted features. Now everything works for me as expected. The attached patch file applies to an installed javavmwrapper-2.3.5 port. You may alternatively just remove those lines from the script file. HTH P.S.: I'm thinking of filing a PR, since it looks like a bug. - -- Alfred Bartsch Data-Service GmbH mailto:bartsch@dssgmbh.de -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk+tB7wACgkQ5QGe2JdVf3g4MwCeO+POVkgOVEYs6yrD4DedfwD3 XacAoLpEI04nrdZq3/iQVFK3QUry/doy =sOgr -----END PGP SIGNATURE----- --------------000705090603050708020508 Content-Type: text/plain; name="patch_javavm.txt" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="patch_javavm.txt" LS0tIGphdmF2bS5vcmlnCTIwMTEtMDktMzAgMDQ6NDA6NTEuMDAwMDAwMDAwICswMjAwCisr KyBqYXZhdm0JMjAxMi0wNS0xMSAwOTowNzo1My4wMDAwMDAwMDAgKzAyMDAKQEAgLTQ5Mywz MCArNDkzLDYgQEAKIAogICAgIHVuc2V0IEpBVkFfSE9NRQogCi0gICAgIyBEZXRlcm1pbmUg bG9jYXRpb24gb2YgYnNkLnBvcnQubWsgaWYgaXQgZXhpc3RzCi0gICAgX0pBVkFWTV9QT1JU U0RJUj0KLSAgICBpZiBbIC1yIC91c3Ivc2hhcmUvbWsvYnNkLnBvcnQubWsgXTsgdGhlbgot ICAgICAgICBfSkFWQVZNX1BPUlRTRElSPWAiJHtfSkFWQVZNX01BS0V9IiAtZiAvdXNyL3No YXJlL21rL2JzZC5wb3J0Lm1rIC1WIFBPUlRTRElSIDI+L2Rldi9udWxsYAotICAgIGZpCi0K LSAgICBfSkFWQVZNX0JTRF9QT1JUX01LPQotICAgIGlmIFsgLW4gIiR7X0pBVkFWTV9QT1JU U0RJUn0iIC1hIC1yICIke19KQVZBVk1fUE9SVFNESVJ9L01rL2JzZC5wb3J0Lm1rIiBdOyB0 aGVuCi0gICAgICAgIF9KQVZBVk1fQlNEX1BPUlRfTUs9IiR7X0pBVkFWTV9QT1JUU0RJUn0v TWsvYnNkLnBvcnQubWsiCi0gICAgZmkKLQotICAgICMgSWYgYnNkLnBvcnQubWsgd2FzIGZv dW5kLCB1c2UgdGhhdCB0byBkZXRlcm1pbmUgdGhlIFZNIHRvIHVzZS4KLSAgICBpZiBbIC1u ICIke19KQVZBVk1fQlNEX1BPUlRfTUt9IiBdOyB0aGVuCi0gICAgICAgIEpBVkFfSE9NRT1g IiR7X0pBVkFWTV9NQUtFfSIgLWYgIiR7X0pBVkFWTV9CU0RfUE9SVF9NS30iIC1WIEpBVkFf SE9NRSBVU0VfSkFWQT15ZXMgMj4vZGV2L251bGxgCi0gICAgICAgIGlmIFsgLW4gIiR7SkFW QV9IT01FfSIgLWEgLWYgIiR7SkFWQV9IT01FfS9iaW4vJHtfSkFWQVZNX1BST0d9IiBdOyB0 aGVuCi0gICAgICAgICAgICBfSkFWQVZNX1BST0dfUEFUSD0iJHtKQVZBX0hPTUV9L2JpbiIK LSAgICAgICAgICAgIHJldHVybiAwCi0gICAgICAgIGVsaWYgWyAtbiAiJHtKQVZBX0hPTUV9 IiAtYSBcCi0gICAgICAgICAgICAgICAtZiAiJHtKQVZBX0hPTUV9L2pyZS9iaW4vJHtfSkFW QVZNX1BST0d9IiBdOyB0aGVuCi0gICAgICAgICAgICBfSkFWQVZNX1BST0dfUEFUSD0iJHtK QVZBX0hPTUV9L2pyZS9iaW4iCi0gICAgICAgICAgICByZXR1cm4gMAotICAgICAgICBmaQot ICAgIGZpCi0KICAgICAjIFRoZW4gdHJ5IHRvIG1ha2Ugc3VyZSB0aGF0ICR7X0pBVkFWTV9D T05GfSBleGlzdHMKICAgICBpZiBbICEgLWUgIiR7X0pBVkFWTV9DT05GfSIgXTsgdGhlbgog ICAgICAgICBlY2hvICIke19KQVZBVk1fUFJPR306IGVycm9yOiBjYW4ndCBmaW5kICR7X0pB VkFWTV9DT05GfSBjb25maWd1cmF0aW9uIGZpbGUiIDE+JjIK --------------000705090603050708020508--
