Hi Bj=C3=B6rn,
Thanks for this. Unfortunately, the new macOS launcher encounters the =
same problem as the one for 5.6. I get the error message that Java 11 is =
required, and I should update Java. Now, without having dug very deep =
into the C code, I can see two possible reasons for this.
The first is that it stops when it encounters the Java internet plugin, =
which in my case is 1.8:
/usr/libexec/java_home -V
Matching Java Virtual Machines (3):
21.0.1 (arm64) "Oracle Corporation" - "Java SE 21.0.1" =
/Library/Java/JavaVirtualMachines/jdk-21.jdk/Contents/Home
21.0.1 (arm64) "Eclipse Adoptium" - "OpenJDK 21.0.1" =
/Library/Java/JavaVirtualMachines/temurin-21.jdk/Contents/Home
1.8.391.13 (x86_64) "Oracle Corporation" - "Java" /Library/Internet =
Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
There is no update available from Java for this plugin.
(You can also see from the above that usr/libexec/java_home does lead to =
the JDK without problem.)
The other possibility is suggested by this code in =
appbundler/native/main.m:
/**
* Searches for a JRE or JDK dylib of the specified version or later.
* First checks the "usual" JRE location, and failing that looks for a =
JDK.
* The version required should be a string of form "1.X". If no version =
is
* specified or the version is pre-1.7, then a Java 1.7 is sought.
*/
NSString * findJavaDylib (
NSString *jvmRequired,
bool jrePreferred,
bool jdkPreferred,
bool isDebugging,
bool exactMatch)
{...}
Since Java is no longer using the nomenclature 1.7, 1.8, etc., then =
maybe this is parsing the name of the version incorrectly? The version =
here is 21, but this method may not be finding it because it expects a =
string of the form 1.x. Might that be the problem?
I will look at this again in more detail when I have more time. =
Meanwhile, I really appreciate any suggestions anybody can make.
Cheers,
Gregory
