Android runtime does not support some JDK method，Please replace!

[iwangxiaodong]

org.jgroups.util.Util.methodNameToAttributeName(final String methodName) and attributeNameToMethodName(String attr_name)
Used android does not support JDK9 method:
java.util.regex.Matcher.appendTail(StringBuilder sb)

Please change!

Thanks!

To rephrase: Android does not support Matcher.appendTail()?

[belaban]

These 2 methods have been in JGroups for years. Why is this relevant now?

[iwangxiaodong]

Android only support https://developer.android.com/reference/java/util/regex/Matcher#appendTail(java.lang.StringBuffer)

[tristantarrant]

Also, with JGroups now requiring JDK 11, I'm not sure this matters.

[iwangxiaodong]

Android JDK vs Oracle JDK: Some methods are missing！
Android only support https://developer.android.com/reference/java/util/regex/Matcher#appendTail(java.lang.StringBuffer)
missing appendTail(StringBuilder sb)

[belaban]

I assume he's using JGroups 4.x?

[belaban]

Anyway, fixed and backported to 4.x

[iwangxiaodong]

Thanks for Fixed！

[iwangxiaodong]

@belaban Sorry:
org.jgroups.util.Util.methodNameToAttributeName(final String methodName) and attributeNameToMethodName(String attr_name):
m.appendReplacement(sb,...); // android 14+ support!

Android 14+：
https://developer.android.com/reference/java/util/regex/Matcher#appendReplacement(java.lang.StringBuilder,%20java.lang.String)

My android app is Android 8.0, use jgroups report: NoSuchMethodException!

If there is no value to modify, I will use the jgroups source code directly，Don't use maven.

Thanks!

Do you have a simple fix? Otherwise I suggest modify the src code and build yourself

[iwangxiaodong]

I am from src code build，only modify Util.methodNameToAttributeName(...) and attributeNameToMethodName(...)：
StringBuffer sb=new StringBuffer(); // StringBuilder sb=new StringBuilder();

Used in Android 8.0 app is works!

I submit a PR? or you directly modify!
